GHSA-7856-g3gv-9wq8: netfoil: Attacker controlled data written to logs
A vulnerability in the netfoil Go library allows attacker-controlled domain names to be written to logs without validation of allowed characters. This improper sanitization could lead to issues depending on how logs are processed or consumed. The vulnerability affects versions prior to 0.3.0. The severity is considered low based on the available information.
AI Analysis
Technical Summary
The netfoil library (github.com/tinfoil-factory/netfoil) contains a vulnerability where domain names are logged without validating that they contain only allowed characters. This is classified as CWE-117 (Improper Output Neutralization for Logs). The impact depends on the usage context of the logs, as malicious input could potentially affect log integrity or downstream log processing. No known exploits are reported. The vulnerability affects versions before 0.3.0.
Potential Impact
The impact is low and context-dependent, relying on how the logs are used. Improperly validated log entries could lead to log injection or corruption, which might affect log parsing or monitoring systems but does not directly compromise system confidentiality, integrity, or availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided. Users should monitor the vendor's repository or advisory channels for updates. Until a fix is available, consider sanitizing or validating domain names before logging them as a workaround.
