RELATES_TOProblem

uses a fixed 32-byte stack buffer to accumulate the date/time fields — from server-controlled LIST output. Tension: a malformed or unusually long date-like token can overflow date_str before the parser reaches strptime.

PERTAIN_TOProblem

it doesn't trigger the unprocessable entity or bad request error — When I'm calling the POST endpoint with partial data or with keys I don't specify in my class. Tension: Even if the auto-created documentation tells me that there are some required fields.

PERTAIN_TOSolution

Use this model for response validation — And you can do use Pydantic validation. Outcome: or use Depends() with Pydantic model.

PERTAIN_TOSolution

or use Depends() with Pydantic model — from fastapi import APIRouter. Outcome: async def add_job(job: Job = Depends()):.

PERTAIN_TOProblem

objects seem to be assumed to arrive in the body in `fastapi` — I'm trying to receive a nontrivial query parameter object. Tension: I've had to do something like this on the server. Outcome: it would be nice for `fastapi` to do this for me directly in the function declaration.

PERTAIN_TOSolution

You can get the actual string which is in json format from `Query` — from `Query`, then `model_validate_json` it to get your `MyParam` object. Tension: it would be nice for `fastapi` to do this for me directly in the function declaration. Outcome: async def get_param( json_str: Annotated[str, Query(description="json-encoded dictionary")], ) -> MyParam: return MyParam.model_validate_json(json_str).

VMS FTP listing parser stack overflow in date_str assembly

PERTAIN_TOProblem

uses a fixed 32-byte stack buffer to accumulate the date/time fields — from server-controlled LIST output. Tension: a malformed or unusually long date-like token can overflow date_str before the parser reaches strptime.

PERTAIN_TOProblem

the property "$schema" is missing — the file that I see in the workflow you shared. Tension: it is replaced by an empty string "" which is treated as a valid JSON property key but a key that is not allowed by SARIF. Outcome: it is referred to as `additional property`.

PERTAIN_TOSolution

cat <<EOF — if you run this command. Tension: performed variable expansion on `$schema`. Outcome: cat <<EOF { "$schema": "https://json.schemastore.org/sarif-2.1.0.json" } EOF.

PERTAIN_TOProblem

a parser path that accumulates filename continuations by reallocating based on strlen(current) + token_length, then memcpy()ing the next token into the tail — While auditing Wget's HTTP Content-Disposition handling. Tension: The code trusts the parsed token boundaries and only strips directory components, but the continuation logic can combine attacker-controlled segments into the final output name. Outcome: This is a useful pattern to watch in header parsers that support RFC2231-style continuations.

tar device density option uses fixed stack buffer with strcpy/sprintf

PERTAIN_TOProblem

when I use Data Conversion Parameters like `EMPTYASNULL` it loads both blanks and nulls as NULL — load blank values as blank and null values as null from a CSV using COPY command in Redshift. Tension: I am expecting blank value in the column for row (with extra='B') but seems like every thing is loaded as null. Outcome: How do I make it blank?

PERTAIN_TOSolution

You want to use the "NULL AS" parameter to COPY. — 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. Outcome: "NULL AS" is likely the easier path.

PERTAIN_TOSolution

view an object's S3 Intelligent Tiering access tier through an S3 Inventory report — Configure S3 Inventory. Tension: This can be enabled on a bucket or prefix level and is generated on a daily or weekly frequency. Outcome: download the file from the S3 Inventory output location and parse if locally or query it via Athena.

PERTAIN_TOProblem

Finding duplicate objects in an S3 bucket by metadata values requires a way to search matching objects

PERTAIN_TOSolution

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

Wget Content-Disposition filename parsing can over-append via RFC2231 continuations

PERTAIN_TOProblem

url_skip_credentials() calls strpbrk(url, "@/?#;") and concludes 'no credentials' if the first stop character is anything other than '@' — GNU Wget through 1.24.5. Outcome: wget connects to one host while logs, security filters, and downstream tools see a different host.

PERTAIN_TOSolution

host := "/var/run/postgresql/" should work — how to ping postgreSQL using Golang just to check that they can talk to each other. Tension: password authentication failed for user "eos_user". Outcome: Successfully connected to PostgreSQL over UNIX socket!

PERTAIN_TOProblem

works only if the db has the same name as the user — I know PostgreSQL can try to connect by default to a DB with the same name. Tension: how can I hard/force specify the DB name? Outcome: As per the docs `dbname` Defaults to be the same as the user name.

PERTAIN_TOSolution

To write an empty value, or a value containing spaces, surround it with single quotes — `lib/pq`/`jackc/pgx`will parse this as "set the password to `name=the-new-c`". Tension: `password= dbname=the-new-c`. Outcome: i.e. `host=localhost port=5432 user=carsUser password='' dbname=the-new-cars sslmode=disable`.

Unclear meaning of @2 in yacc grammar action

PERTAIN_TOSolution

Use @n to access the location structure for the nth symbol in the production

PERTAIN_TOProblem

I'm getting a syntax error with ALTER TABLE — I hooked up H2, but. Tension: It looks like H2 doesn't have the `ALTER TABLE OWNER to ` command. Outcome: Has anyone seen this before or know a clever way to get around this?

PERTAIN_TOProblem

But no error is found... — I'm trying to use Psalm to detect SQL Injections. Tension: I have no config file. Outcome: I edited the config file `psalm.xml`.

PERTAIN_TOSolution

I edited the config file `psalm.xml` — I enabled the `pdo` extension. Outcome: And now I just run the commande like so.

PERTAIN_TOProblem

Sigma rules do not work reliably on Sysmon .csv logs

PERTAIN_TOSolution

instead of .csv logs, I use .evtx logs — Sysmon logs in this format. Tension: This is the alternative solution that seems to work fine for me. Outcome: used `chainsaw` from https://github.com/WithSecureLabs/chainsaw.

PERTAIN_TOProblem

expr-eval comes with a lot of possibilities like ternary conditions, variable declarations and so on. — I want to re-run the calculation with the incoming data on the server using PHP. Tension: there is no equivalent library for PHP. Outcome: would be the way of running such a verification?

PERTAIN_TOSolution

you're going to need to define your syntax very strictly, implement your own parser then hand off the final expression to eval. — if you allow anything which is not an arithmentic operator or a number to be 'eval'ed. Tension: the code is exploitable. Outcome: hand off the final expression to eval.

PERTAIN_TOProblem

nginx output a new line in access.log — When I access https://home.aaa.com/actuator/prometheus;%2f..%2f..//. Tension: I expect nginx deny this request too. Outcome: there is not a log in nginx error_log.

PERTAIN_TOSolution

Then it not match the `location /actuator/` — Here is the illustration,. Tension: Which will in the nginx `$uri` valable will be `/`. Outcome: return 403 $uri;.

PERTAIN_TOProblem

How can I parse the generated binary log file "SRTMBoot.dat" so that I get human readable content? — I can generate a log via the command 'tpmtool.exe gatherlogs'.

PERTAIN_TOSolution

I have used TCGLogTools (a powershell based parser) in the past. — With this tool you can convert the logs in readable json files. Outcome: ConvertTo-TCGEventLog -LogPath s:\temp\tpm\SRTMBoot.dat | ConvertTo-Json -Depth 8 | Out-File 's:\temp\tpm\SRTMBoot.json'.

PERTAIN_TOReport

Archive symbol table parsing needs strict bound checks before copying member names

PERTAIN_TORootCause

Archive::read_armap() loads the entire symbol map, then iterates names via strlen(pnames + name_offset) while only checking total consumed length after the loop. — gold/archive.cc. Tension: The general fix pattern is to validate each offset/length against the containing buffer before any strlen/memcpy/assign operations, not after the fact. Outcome: Archive::setup() reads the archive header and caches the extended-name table.

PERTAIN_TOProblem

parses archive symbol tables and extended-name tables from attacker-controlled .a files — gold linker. Tension: If the archive layout and name offsets disagree, later string handling can walk past the end of the cached name table or construct malformed member names. Outcome: copying or slicing names from raw archive metadata after only partial validation.

PERTAIN_TOSolution

Harden archive parsing by checking each symbol-name offset is within names_size before calling strlen — gold/archive.cc. Outcome: Prefer explicit bounded scans (memchr/strnlen) and fail closed on malformed archives.

PERTAIN_TOProblem

Tension: I would like to ask if there is a way to use the parser to extract only `create table` statements, ignoring everything else.

PERTAIN_TOSolution

you get the same exception that you would get if the parser encountered unsupported syntax — After reading the files, do some heuristics where you remove any `create function` or similar statement. Tension: I cannot modify these DDL files. Outcome: A pragmatic solution here is to match `create( or replace)? function.*?\\$\\$.*?\\$\\$.*?;` or similar.

PERTAIN_TOProblem

Spring JPA fails when executing an UPDATE on the Oracle table, throwing “Unable to bind parameter #7 - Invalid column index”.

PERTAIN_TOProblem

Cannot resolve symbol 'PostgreSQLParser'. Outcome: the compiled happened successfully.

PERTAIN_TOSolution

Use `-Didea.max.intellisense.filesize=5000` — in the vmoptions cofig file. Tension: it incerased the limit to 5 MB and solves the problem. Outcome: solves the problem.
