Vulnerability from github – Published: 2022-06-25 07:12 – Updated: 2023-10-02 11:02

Summary

Path traversal mitigation bypass in OctoRPKI

Details

Impact

The existing URI path filters in OctoRPKI (version < 1.4.3) mitigating Path traversal vulnerability could be bypassed by an attacker. In case a malicious TAL file is parsed, it was possible to write files outside the base cache folder.

CVE-2021-3907 (GCVE-0-2021-3907)

Vulnerability from cvelistv5 – Published: 2021-11-11 21:45 – Updated: 2024-09-17 03:18

Title

Arbitrary filepath traversal via URI injection

Summary

OctoRPKI does not escape a URI with a filename containing "..", this allows a repository to create a file, (ex. rsync://example.org/repo/../../etc/cron.daily/evil.roa), which would then be written to disk outside the base cache folder. This could allow for remote code execution on the host machine OctoRPKI is running on.

Severity ?

7.4 (High)
