CVE-2023-41056: Redis vulnerable to integer overflow in certain payloads
Noroxi assessment
Priority: Monitor (action score 33/100)
- 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: 2.5% (FIRST EPSS); higher than 85.3% 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. Special conditions such as timing or configuration are required.
- Fixed version: redis redis 7.0.15.
Low priority for now. Upgrade to redis redis 7.0.15 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
Redis is an in-memory database that persists on disk. Redis incorrectly handles resizing of memory buffers which can result in integer overflow that leads to heap overflow and potential remote code execution. This issue has been patched in version 7.0.15 and 7.2.4.
