Broken Crypto Authentication Practices

cluster-35

Encryption or identity checks get implemented without message authentication or correct key/parameter handling—e.g., AES-CBC without integrity, unmanaged IV/key lifecycles, and insufficient JWKS trust validation—so attackers can tamper, substitute, or replay data and tokens.

INSTANCE_OFProblem

createPrivateKey() throws error:1E08010C:DECODER routines::unsupported on Vercel

INSTANCE_OFProblem

Safari DevTools console shows full details, but JS code only gets "TypeError: Load failed"

INSTANCE_OFProblem

curl: (60) SSL certificate problem: unable to get local issuer certificate — curl -sL -k https://sentry.io/get-cli/ | bash. Outcome: Ok disabling internet security provider during the time of the installation worked for me.

INSTANCE_OFProblem

hash could not be identified — When I insert the username and password in my fastapi login form. Tension: The passwords in the database are already hashed (I'm using the same database from the Django project). Outcome: I've also tried `password = form.get("password")`, and the error still pops up.

INSTANCE_OFProblem

This file is checked in to source control and includes the clear text password. — I have a `nuget.config` file. Tension: I don't want the password to be visible in source control. Outcome: Is it possible to use a secret/env variable to replace the password?

INSTANCE_OFProblem

the permission policies in the template don't match what I would expect — The template.yaml for the 'producer' application looks like this. Outcome: So the repost doc is correct.

INSTANCE_OFProblem

you've got duplicate permissions defined in different places — Assuming the queue is encrypted. Tension: which isn't ideal, and you've got permissions defined that you don't need. Outcome: neither producer nor consumer need `kms:Encrypt`.

INSTANCE_OFProblem

Is there a way to not make a S3 bucket encrypted by default or may be remove the added encryption? — Amazon S3 now applies server-side encryption with Amazon S3 managed keys (SSE-S3) as the base level of encryption for every bucket in Amazon S3. Tension: AWS recently changed their policy. Outcome: No. It is not allowed to disable encryption.

INSTANCE_OFProblem

the data from encoding a certificate to a string is over the max size of Version 40 of QR. Tension: how QR decoding websites were able to decode the QR and I wasn't. Outcome: I now use `Brotli4j` to compress the certificates bytes BEFORE encoding to a QR.

INSTANCE_OFProblem

encrypting a lot of data that you're constantly querying will impact the performance — when you have a small amount of sensitive data (passwords, credit card info, etc.). Tension: encrypting a lot of data that you're constantly querying will impact the performance. Outcome: yes, TDE is the best choice because it works in a different way.

INSTANCE_OFProblem

I did not include network_security_config.xml in my Android Application. — The target SDKs of my android app are android:minSdkVersion="28" and android:targetSdkVersion="35". Tension: Is it okay if I won't create Network Security Configuration since I am targeting SDKs >28 and <35? Outcome: No, you don't need to add it.

INSTANCE_OFProblem

I’m referring to the official ESP-IDF documentation — after Secure Boot V2 has already been enabled. Tension: This command erases the entire flash, including the bootloader region (< 0x8000). Outcome: There is very little interaction between Secure Boot and Flash Encryption.

INSTANCE_OFProblem

how can I observe that the running kafka broker is using the new stores/certs ? — When changing the Apache Kafka server's trust- or keystore. Tension: Do Kafka rereads the stores on each new connection ? Outcome: The messages will only appear if the content of the trust- or keystore has changed.

INSTANCE_OFProblem

as long as the keys are shipped together with the apk, they are not secured — Is there a way to safely deliver the SDK keys with the Android app? Tension: there is still a simple way to get them. Outcome: no matter where the SDK keys are stored.

INSTANCE_OFProblem

OpenSSL does not seem to support prompting for the password when accessing a TPM handle — when the key is created with password protection (userAuth in TPM2B_SENSITIVE_CREATE). Tension: it fails silently or with cryptic errors. Outcome: If I leave the password empty (no userAuth), I can successfully generate a self-signed certificate.

INSTANCE_OFProblem

the students are still able to guess the correct file descriptor of stdout and write to it. Tension: this is not secure as a student can do `int student_function(int foo) { printf("OK"); exit(1) }` and pass all tests. Outcome: would it make sense to fork the process, and use some magic based on seccomp etc?

INSTANCE_OFProblem

Is it possible to prevent screen recording while allowing screnshots in android application? — android application. Tension: FLAG_SECURE, but it prevent both screenshots and screen recording simutaneously. Outcome: No, there isn't.

INSTANCE_OFProblem

Users can modify it using the developer tools and access premium features for free. — I am developing a Chrome extension where some features require payment. However, I have a problem. Tension: If I verify the payment status only through the server, then users won’t be able to use the extension offline. Outcome: There is no fool-proof licensing system for client-side (offline) extensions.

INSTANCE_OFProblem

TEEC_InvokeCommand returns 0xffff0008 for nvhwkey-app file encryption and decryption

INSTANCE_OFProblem

application.properties contains sensitive configuration and database credentials that could be exposed if committed to a Git repository.

INSTANCE_OFProblem

you have to load your certificate and private key in the client side code — connect to my server using my cert and the TrustStore. Tension: I'm still able to authenticate myself and connect. Outcome: now I'm able to connect to my server using my cert and the TrustStore.

INSTANCE_OFProblem

A user with DBA privileges can grant DBA to another user inside an invoker-rights (AUTHID CURRENT_USER) PL/SQL function executed by the first user, effectively escalating the second user's privileges. The experiment shows that executing BBB's function from AAA results in BBB gaining DBA privileges.

INSTANCE_OFProblem

want to ensure that the certificate renews automatically without manual intervention — I'm using `Let's Encrypt` for the certificate. Tension: Currently, I manually add the `_acme-challenge` record and secret to the DNS server.

INSTANCE_OFProblem

DataStore does not offer encryption — I'm using Jetpack DataStore in my Android application and want to ensure it's secure enough for storing sensitive data. Tension: could it potentially be decrypted by an attacker? Outcome: Using DataStore for the actual storage should be fine, and you can encrypt/decrypt your data yourself.

INSTANCE_OFProblem

I need a way to sandbox the code and limit its permissions. — dynamically loading and executing third-party code. Outcome: there are (currently) no alternatives for running untrusted Java code within a Java application.

INSTANCE_OFProblem

I can still connect in ‘anonymous’ mode — I'm trying to set up authentication for my OPC-UA server. Tension: I don't want my clients to be able to connect to my server in ‘anonymous’ mode. Outcome: the certificate login is blocked, which is fair enough.

INSTANCE_OFProblem

Never store private keys or the corresponding certificate files (.pfx/p12) on an unencrypted file system. — the private key files on an encrypted file system. Tension: private keys or the corresponding certificate files (.pfx/p12) on an unencrypted file system.

INSTANCE_OFProblem

I can't figure out how to deny access to NT AUTHORITY\NETWORK. — a named pipe locally only. Tension: all named pipes are accessible remotely. Outcome: How do I do that?

INSTANCE_OFProblem

want to generate a new key pair — I am using dotenvx in my project. Tension: can't find any information on how to do this from the docs/online. Outcome: Run `dotenvx encrypt`.

INSTANCE_OFProblem

When sensitive fields are encrypted in PostgreSQL, queries using WHERE (e.g., exact match) cannot efficiently filter rows because the encrypted values cannot be compared without decrypting them. This makes encrypted-field searches slow and impractical at scale.

INSTANCE_OFProblem

make sure that users do not reuse their recent passwords; are too similar to their current password. Tension: how do systems enforce the not being similar test without having to store the passwords in plain text in the database? Outcome: keeping a table of the hashes for comparison.

INSTANCE_OFProblem

I have to leak user login credentials — if you preform a `Box::leak(Box::new(value))` and receive a `&'static`. Tension: those credentials will not be cleared from the memory on application, exit. Outcome: The operating system will free all memory allocated by a process when that process terminates.

INSTANCE_OFProblem

Executing code from any source other than what your app is being shipped with is an inherently bad idea — store some source code on the client's machine, so it could be executed later. Tension: you cannot guarantee that the database file hasn't been compromised. Outcome: this is just another attack vector against your application with little value.

INSTANCE_OFProblem

Recently they changed the security protocol to TLSV1.2 and so I can no longer access it. Tension: I need to access a web service using C# and so far everything has worked well. Outcome: System.Net.WebException: The underlying connection was closed: Unexpected error on a send.

INSTANCE_OFProblem

they are printed out — After the three passwords have been overwritten. Tension: it is definitely possible that a `String` instance of your `char` array was created somewhere, and that this `String` can be found in a heapdump.

INSTANCE_OFProblem

I want to ensure that these API keys are stored securely in my database. — I'm building a REST API that uses API keys for authentication. Tension: Should I hash API keys before storing them in the database, similar to user passwords? Outcome: I reviewed the OWASP guidelines but couldn't find a definitive recommendation on this topic.

INSTANCE_OFProblem

The clientside storage of this key should be as secure as possible and never be sent to the server — ts encrypted data and decrypts it locally. Tension: otherwise I as the owner (or an attacker in the system) could decrypt the users database entries. Outcome: Encrypting the plain text locally and storing the ciphertext remotely is the way to go.

INSTANCE_OFProblem

I get the error: "The security descriptor structure is invalid" — I'm trying to create a key in the TPM with the help of the NCrypt library and restrict the access to only my application in C++.

INSTANCE_OFProblem

Cannot use an ACM-PCA-issued certificate to sign another certificate

INSTANCE_OFProblem

Can I change my grade to an 'A' and also get access to the shell? — grade management program. Tension: To award an A+ grade, please enter the passcode. Outcome: you'll pass the authentication.

INSTANCE_OFProblem

I need to know if there's a way to identify if each of those individual libraries can be verified for FIPS 140-2 compliance? — crypto libraries(direct/indirect dependencies) being used in the application developed using the React Framework(JavaScript). Outcome: FIPS 140-2 compliance is not a self assessed compliance.

INSTANCE_OFProblem

return (*env)->NewStringUTF(env, "sk-XXXXXXXXXkeyXXXXXXXXX"); — storing the key in a `.c` file and returning it to my Kotlin code. Tension: Is this secure? Or what is the better approach to store API Keys.

INSTANCE_OFProblem

Anyone can rebuild your APK in debugging mode and just put a breakpoint at the right point in your program. — I'm using `openAI` directly in my Android Kotlin App. Tension: No matter how convoluted and complex you make the process of getting the API key, at some point it will sit in memory. Outcome: Do not do this.

INSTANCE_OFProblem

The option to create dynamic certificates in ZAP is not available. — I am running it on a local machine. Tension: Does anyone know whether it's been removed? If not, where/how do I get to it? Outcome: It has not been removed.

INSTANCE_OFProblem

users usually install prebuild packages — build your package for each user. Tension: this counter-measure becomes useless. Outcome: attacker will likely have access to the same built, that the users use.

INSTANCE_OFProblem

Is there any ways to restrict the access to only allowed code or protect the code somehow technically from being stolen? — We use Git as a repository for hosting our code. Tension: The only thing we came up with is to create separate repositories for the abroad developer so they only access the allowed part and only work on it. Outcome: There are some drawbacks for the merging to the main code base, conflicts and so on.

INSTANCE_OFProblem

setting the FLAG_SECURE is not working at all — in Android 14. Tension: to achieve the Screen Privacy and can anybody provide some work-around.

INSTANCE_OFProblem

The Python doc says: By default, the `__hash__()` values of str and bytes objects are “salted” with an unpredictable random value. — the algorithm used for computing hash() of numbers is deterministic. Tension: Why an attacker can not use integers to run DoS by the same reason? Outcome: The security benefits of the change won out over the performance impact for strings and `bytes` objects, but not for numeric types.

INSTANCE_OFProblem

I don't want to hardcode it. — How to make secure info of my sign app when I want to release my app. Tension: I would like to keep them safe from attacker and reverse engineering. Outcome: externalizing secrets.

INSTANCE_OFProblem
