CVE-2024-51737 | RediSearch Integer Overflow with LIMIT or KNN arguments can lead to RCE

RediSearch is a Redis module that provides querying, secondary indexing, and full-text search for Redis. An authenticated redis user executing FT.SEARCH or FT.AGGREGATE with a specially crafted LIMIT command argument, or FT.SEARCH with a specially crafted KNN command argument, can trigger an integer overflow, leading to heap overflow and potential remote code execution. This vulnerability is fixed in 2.6.24, 2.8.21, and 2.10.10. Avoid setting value of -1 or large values for configuration parameters MAXSEARCHRESULTS and MAXAGGREGATERESULTS, to avoid exploiting large LIMIT arguments.

CVSS metrics for this CVE.

Base score Version Severity Vector Exploitability Impact Score source
7.0 3.1 HIGH
CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:H)
Even with access, the exploit needs extra luck, timing, or a fussy environment to actually work.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
