CVE-2023-41053: Redis SORT_RO may bypass ACL configuration

LowCVSS 3.3 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 13/100)

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: 0.29% (FIRST EPSS).
Someone with local access to the system 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 (AlmaLinux:9) 7.2.6-1.module_el9.5.0+130+36ae7635; redis-devel (AlmaLinux:9) 7.2.6-1.module_el9.5.0+130+36ae7635; redis-doc (AlmaLinux:9) 7.2.6-1.module_el9.5.0+130+36ae7635.

Low priority for now. Upgrade to redis (AlmaLinux:9) 7.2.6-1.module_el9.5.0+130+36ae7635; redis-devel (AlmaLinux:9) 7.2.6-1.module_el9.5.0+130+36ae7635; redis-doc (AlmaLinux:9) 7.2.6-1.module_el9.5.0+130+36ae7635 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

Redis is an in-memory database that persists on disk. Redis does not correctly identify keys accessed by `SORT_RO` and as a result may grant users executing this command access to keys that are not explicitly authorized by the ACL configuration. The problem exists in Redis 7.0 or newer and has been fixed in Redis 7.0.13 and 7.2.1. Users are advised to upgrade. There are no known workarounds for this vulnerability.
