CVE-2022-35951: Redis subject to Integer Overflow leading to Remote Code Execution via Heap Overflow

CriticalCVSS 9.8 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Plan (action score 40/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 3.9% (FIRST EPSS); higher than 90.4% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: redis (Alpine:v3.16) 7.0.5-r0; redis (Debian:12) 5:7.0.5-1; redis (openSUSE:Tumbleweed) 7.0.5-1.1.
  • Severity is disputed: the assigning authority (CNA) scores it 7.0, NVD 9.8.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Add it to your regular patch cycle. Upgrade to redis (Alpine:v3.16) 7.0.5-r0; redis (Debian:12) 5:7.0.5-1; redis (openSUSE:Tumbleweed) 7.0.5-1.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Redis is an in-memory database that persists on disk. Versions 7.0.0 and above, prior to 7.0.5 are vulnerable to an Integer Overflow. Executing an `XAUTOCLAIM` command on a stream key in a specific state, with a specially crafted `COUNT` argument may cause an integer overflow, a subsequent heap overflow, and potentially lead to remote code execution. This has been patched in Redis version 7.0.5. No known workarounds exist.
