CVE-2024-39932: Gogs allows argument injection during the previewing of changes
Gogs through 0.13.0 allows argument injection during the previewing of changes.
CVSS 9.9 Critical EPSS 17.3% · p97
Should you act?
High exploit likelihood
EPSS ranks it in the top 5% of all CVEs for likely exploitation in the next 30 days. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.
- Not in CISA KEV, but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 17.3%, percentile 97: FIRST’s model estimates a 17.3% chance of exploitation activity in the next 30 days, higher than 97% of all scored CVEs (very high). EPSS is a probability, not a verdict.
- Needs an account (low (any account)). Exposure depends on who can log in.
- Only applies if your dependency tree includes
gogs.io/gogs(Go) <= 0.13.0, fixed in 0.13.1. Check your lockfile, including transitive dependencies.
What it is
Gogs through 0.13.0 allows argument injection during the previewing of changes.
From the GitHub advisory
Impact
Unprivileged user accounts can write to arbitrary files on the filesystem. We could demonstrate its exploitation to force a re-installation of the instance, granting administrator rights. It allows accessing and altering any user's code hosted on the same instance.
Patches
Unintended Git options has been ignored for diff preview (https://github.com/gogs/gogs/pull/7871). Users should upgrade to 0.13.1 or the latest 0.14.0+dev.
Workarounds
Weakness type: CWE-94.
