CVE-2024-21645: Pyload ng Pyload Log Injection Vulnerability Vulnerability
MODERATECVE-2024-21645 is a MODERATE (CVSS 5.3) pyload log injection vulnerability vulnerability (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')) affecting Pyload ng libraries in the PyPI ecosystem. The issue involves pyload log injection vulnerability. Remediation is available by upgrading affected packages to version 0.5.0b3.dev77.
CVE-2024-21645 at a Glance
Security Impact
CVSS: 5.3
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N).
How to Fix CVE-2024-21645
To remediate this vulnerability, upgrade all affected Pyload ng dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
pip install pyload-ng>=0.5.0b3.dev77Run the following command in your project directory to verify that all resolved dependencies use the patched release:
pip show pyload-ngHow to Check if You Are Affected
To determine whether your Python environment is affected by CVE-2024-21645, inspect your installed packages using pip:
pip show pyload-ngAnalyze the terminal output to locate any version of Pyload ng in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.5.0b3.dev77), your application is affected.
Note: The pip show pyload-ng command checks currently installed packages in your active Python environment.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection'), where the product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. In Pyload ng, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"details" : "### Summary\nA log injection vulnerability was identified in `pyload`. This vulnerability allows any unauthenticated actor to inject arbitrary messages into the logs gathered by `pyload`.\n\n### Details\n`pyload` will generate a log entry when attempting to sign in with faulty credentials. This entry will be in the form of `Login failed for user 'USERNAME'`. However, when supplied with a username containing a newline, this newline is not properly escaped. Newlines are also the delimiter between log entries. This allows the attacker to inject new log entries into the log file.\n\n### PoC\nRun `pyload` in the default configuration by running the following command\n```\npyload\n```\n\nWe can now sign in as the pyload user and view the logs at `http://localhost:8000/logs`.\n\n\nAny unauthenticated attacker can now make the following request to inject arbitrary logs.\n\n```\ncurl 'http://localhost:8000/login?next=http://localhost:8000/' -X POST -H 'Content-Type: application/x-www-form-urlencoded' --data-raw $'do=login&username=wrong\\'%0a[2024-01-05 02:49:19] HACKER PinkDraconian THIS ENTRY HAS BEEN INJECTED&password=wrong&submit=Login'\n```\n\nIf we now were to look at the logs again, we see that the entry has successfully been injected.\n\n\n### Impact\nForged or otherwise, corrupted log files can be used to cover an attacker’s tracks or even to implicate another party in the commission of a malicious act.\n",
