CVE-2023-36824: Heap overflow in COMMAND GETKEYS and ACL evaluation in Redis
Noroxi assessment
Priority: Plan (action score 58/100)
- 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: 77.4% (FIRST EPSS); higher than 99.5% of all records.
- Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: redis (Alpine:v3.16) 7.0.12-r0; redis (Debian:12) 5:7.0.15-1~deb12u1; redis (Debian:13) 5:7.0.12-1.
Add it to your regular patch cycle. Upgrade to redis (Alpine:v3.16) 7.0.12-r0; redis (Debian:12) 5:7.0.15-1~deb12u1; redis (Debian:13) 5:7.0.12-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
Redis is an in-memory database that persists on disk. In Redit 7.0 prior to 7.0.12, extracting key names from a command and a list of arguments may, in some cases, trigger a heap overflow and result in reading random heap memory, heap corruption and potentially remote code execution. Several scenarios that may lead to authenticated users executing a specially crafted `COMMAND GETKEYS` or `COMMAND GETKEYSANDFLAGS`and authenticated users who were set with ACL rules that match key names, executing a specially crafted command that refers to a variadic list of key names. The vulnerability is patched in Redis 7.0.12.
