CVE-2024-42360: Command Injection in sequenceserver
SequenceServer lets you rapidly set up a BLAST+ server with an intuitive user interface for personal or group use.
CVSS 9.3 Critical EPSS 0.6% · p47
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 0.6%, percentile 47: FIRST’s model estimates a 0.6% chance of exploitation activity in the next 30 days, higher than 47% of all scored CVEs (low). 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
sequenceserver(RubyGems) < 3.1.2, fixed in 3.1.2. Check your lockfile, including transitive dependencies.
What it is
SequenceServer lets you rapidly set up a BLAST+ server with an intuitive user interface for personal or group use. Several HTTP endpoints did not properly sanitize user input and/or query parameters. This could be exploited to inject and run unwanted shell commands. This vulnerability has been fixed in 3.1.2.
