2DescriptionCVE.org
An out-of-bounds write vulnerability has been reported to affect several QNAP operating system versions. If a remote attacker gains a user account, they can then exploit the vulnerability to modify or corrupt memory.
We have already fixed the vulnerability in the following versions: QTS 5.2.5.3145 build 20250526 and later QuTS hero h5.2.5.3138 build 20250519 and later
AnalysisAI
An out-of-bounds write vulnerability has been reported to affect several QNAP operating system versions. Rated high severity (CVSS 7.1), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
Technical ContextAI
This vulnerability is classified as Out-of-bounds Write (CWE-787), which allows attackers to write data beyond allocated buffer boundaries leading to code execution or crashes. An out-of-bounds write vulnerability has been reported to affect several QNAP operating system versions. If a remote attacker gains a user account, they can then exploit the vulnerability to modify or corrupt memory. We have already fixed the vulnerability in the following versions: QTS 5.2.5.3145 build 20250526 and later QuTS hero h5.2.5.3138 build 20250519 and later Affected products include: Qnap Qts, Qnap Quts Hero.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate write boundaries, use memory-safe languages, enable compiler protections (ASLR, stack canaries).
