I found a trick forking the jvm, below sbt config — for unit tests. Tension: must be the same idea for classic run (fork + javaOptions).

REQUIRESSolution

Use S3 Metadata tables and query e_tag with Athena or another Iceberg-compatible tool to locate duplicate objects

REQUIRESSolution

you need to use the `location` function instead — DeltaTable.createOrReplace(spark). Tension: you provide a path to a bucket.

REQUIRESSolution

you likely need to write your own `org.apache.ignite.internal.processors.security.GridSecurityProcessor` implementation — When customizing security. Tension: the default `org.apache.ignite.internal.processors.authentication.IgniteAuthenticationProcessor` only supports authenticating thin clients. Outcome: GridGain has a more advanced implementation with LDAP/OpenID/JAAS integrations and authorization/permissions/RBAC.

REQUIRESSolution

Yes this is secure because Apache does not make files starting with a dot, like '.htaccess' public. — Laravel project through Zap Scanner Application. Tension: I am not sure if it is normal, or I should move the .htaccess to different folder? Outcome: I should move the .htaccess to different folder?

REQUIRESSolution

Set up and secure a proxy — in front of your Django application. Tension: Nginx, Tomcat, Apache, etc. Outcome: in front of your Django application.

REQUIRESSolution

EvidenceBean evidenceBean = new EvidenceBean(); — authDecisionStatementData.setEvidence(evidenceBean);. Tension: The object hierarchy directly mirrors the SAML XML structure. Outcome: evidenceBean.setAssertions(List.of(evidenceAssertion));.

REQUIRESSolution

producer-consumer design to process a list of objects. Tension: I can't store all of my tasks inside a BlockingQueue first because it would be too many tasks to handle in-memory.

REQUIRESSolution

Configure static and media serving for the production deployment, e.g., use WhiteNoise for static files and ensure media is served (such as adding URL patterns using django.views.static.serve for STATIC_ROOT and MEDIA_ROOT, or correctly configuring Apache/static file handling).

PERTAIN_TODomain

Security

PERTAIN_TOProblem

the default servlet is disabled by default in spring since 2020 — in spring boot. Tension: there are no web.xml files in the resulting jar. Outcome: reactivate the default servlet with the property "server.servlet.register-default-servlet=true".

PERTAIN_TOProblem

bash initializes, initialize_shell_variables() in variables.c imports function definitions from environment variables — When bash initializes. Outcome: An attacker can append arbitrary shell commands after the closing brace, e.g., VAR='() { :;}; /usr/bin/id', and they will be executed.

FIXED_BYSolution

Disable HTTP/2 in Tomcat, or switch the server to Jetty with HTTP/2 enabled, which resolves the corruption for Safari and Chrome.

IMPLEMENTATION_OFComponent

kafka

AFFECTSRootCause

Kafka has its own internal zookeeper dependancy — We use Helm and ArgoCD. Outcome: zookeeper: persistence: storageClass: csi-disk.

AFFECTSRootCause

because module java.base does not export sun.nio.ch to unnamed module @0x7b8a43da.

AFFECTSRootCause

But all the options above are ignored by `maven-surefire-plugin` — Configuring `pom.xml`. Tension: I have to either set `surefire.exitTimeout` or `` property with increased value in seconds. Outcome: maven-surefire-plugin.

AFFECTSRootCause

Ceph and the AWS SDK use different checksum algorithms, causing a checksum mismatch

AFFECTSRootCause

You are specifying CSV which comes with implied quoting of fields. — If you really need to distinguish between ,, and ,"",. Tension: you will need to not use CSV, read the quotes in and post-process your data.

AFFECTSRootCause

S3 object metadata is not directly queryable without S3 Metadata or an external index

AFFECTSRootCause

Class org.apache.hadoop.fs.s3a.S3AFileSystem not found — moving plugin jar to `/opt/flink/plugins/s3-fs-hadoop/` in my Dockerfile. Tension: it is redundancy and should work without it ? Outcome: plugin is in the right folder.

AFFECTSRootCause

plugin activation methods were mixed by using both Dockerfile setup and ENABLE_BUILT_IN_PLUGINS

AFFECTSRootCause

Your table definition references a file in B2 — It should reference a 'directory' (technically, a prefix, since directories don't exist in cloud object storage). Tension: Remove `data.csv` from the table definition. Outcome: it should work.

AFFECTSRootCause

you have a lot of writers that write small Parquet files — If you have CDC kind of workloads. Tension: that is going to be a problem. Outcome: it will have to do several requests to write just a small portion of data.

AFFECTSRootCause

the number of incoming requests to S3 exceeds the capacity of the connection pool — multiple threads attempting to access S3 concurrently. Tension: contention for connections can cause timeouts. Outcome: The number of connections available is controlled by the property `http-client.apache.max-connections`.

AFFECTSRootCause

it should be registered table name, like, in Hive Metastore. Tension: you provide a path to a bucket. Outcome: you need to use the `location` function instead.

AFFECTSRootCause

The messages will only appear if the content of the trust- or keystore has changed. — After reconfiguration of trust- or keystore. Outcome: Created new CLIENT SSL engine builder with keystore ...

AFFECTSRootCause

The default `org.apache.ignite.internal.processors.authentication.IgniteAuthenticationProcessor` only supports authenticating thin clients with Basic authentication (login/password) while thick clients are considered trusted — When customizing security. Tension: the Security Processor code will be called from all kinds of sensitive contexts while processing requests. Outcome: write your own `org.apache.ignite.internal.processors.security.GridSecurityProcessor` implementation.

AFFECTSRootCause

the default servlet is disabled by default in spring since 2020 — looking if they reactivate the default servlet with the property "server.servlet.register-default-servlet=true". Tension: there are no web.xml files in the resulting jar. Outcome: the readonly property can also be set programatically.

AFFECTSRootCause

The default value of the readonly param is true, according to Tomcat's docs, and the CVE itself. — if I don't have `readonly` in my web.xml? Tension: That means that writes are not enabled, if the readonly param is missing from the servlet configuration. Outcome: writes are not enabled, if the readonly param is missing from the servlet configuration.

AFFECTSRootCause

This vulnerabilities come from its dependencies. Outcome: it references jetty-server 8.2.0.v20160908.

AFFECTSRootCause

I have a dictionary that contains the role names and their corresponding permissions. — programmatically. Tension: I'm not entirely sure how to use it to create these custom roles programmatically.

AFFECTSRootCause

creating a file named security.json — starting Solr in standalone mode (not cloud). Outcome: Follow the instructions provided in the Apache Solr official documentation for setting up the Basic Authentication Plugin.

AFFECTSRootCause

Apache does not make files starting with a dot, like '.htaccess' public. — When I type http://127.0.0.1:8000/.htaccess in the browser. Tension: it stated ".htaccess Information Leak" as a medium level risk. Outcome: Yes this is secure.

AFFECTSRootCause

`~` indicates regex — we are searching for `index.php` or empty string (which is root directory in this case). Outcome: we are searching for `index.php` or empty string (which is root directory in this case).

AFFECTSRootCause

in the world of CodeIgniter 4. Tension: if they don't exist already. Outcome: (new CodeIgniter\Config\DotEnv(ROOTPATH))->load();.

AFFECTSRootCause

there is more than one mappable servlet in your servlet context — This is because there is more than one mappable servlet in your servlet context: {org.apache.jasper.servlet.JspServlet=[*.jsp, .jspx], javax.faces.webapp.FacesServlet=[/faces/, *.jsf, *.faces, *.xhtml], org.springframework.web.servlet.DispatcherServlet=[/]}. Tension: This method cannot decide whether these patterns are Spring MVC patterns or not. Outcome: For each MvcRequestMatcher, call MvcRequestMatcher#setServletPath to indicate the servlet path.

AFFECTSRootCause

it can contain false positives (very common with the OWASP tool) and "disputed" vulnerabilities — OWASP dependency check tool. Tension: false positives (very common with the OWASP tool). Outcome: must be examined carefully.

AFFECTSRootCause

trying to see exactly which problem I have — openssl s_client -debug -connect localhost:9093 -tls1_2 -showcerts. Tension: I generated my truststore, ca and keystore different way but they alway lead to the same problem. Outcome: When you sign your certificate, include a Subject Alternative Name (SAN) record.

AFFECTSRootCause

These look like someone is trying to scan my VM/app. Tension: to find `.env` file, login credentials, etc. Outcome: This is typical in the modern world because there are so many scanning bots out there.

AFFECTSRootCause

this is because the running instance uses some dependencies which caused such a conflict — when I deployed the code on a running instance. Tension: resulted in this error. Outcome: uses some dependencies which caused such a conflict.

AFFECTSRootCause

Conflicting or duplicated redirect/SSL behavior between Apache (.htaccess) and Cloudflare causes requests for example.com to bounce between HTTP/HTTPS and/or www/non-www until the redirect limit is hit.

AFFECTSRootCause

embed a custom TrueType font (FreeSans.ttf) with subsetting enabled — Apache PDFBox to create a PDF with form fields. Tension: displays gibberish characters instead of the actual text. Outcome: Never subset the font for acroform fields.
