CVE-2024-33434: tiagorlampert CHAOS vulnerable to arbitrary code execution
An issue in tiagorlampert CHAOS v5.0.1 before 1b451cf62582295b7225caf5a7b506f0bad56f6b and 24c9e109b5be34df7b2bce8368eae669c481ed5e allows a remote attacker to execute arbitrary code via the unsafe concatenation of the filename argument into the buildStr string without any sanitization or filtering.

Should you act?
Critical and remotely reachable
No known exploitation yet, but it is network-reachable without credentials. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.
- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 1.4%, percentile 71: FIRST’s model estimates a 1.4% chance of exploitation activity in the next 30 days, higher than 71% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes
github.com/tiagorlampert/CHAOS(Go) < 0.0.0-20220716132853-b47438d36e3a, fixed in 0.0.0-20220716132853-b47438d36e3a. Check your lockfile, including transitive dependencies.
