A security control designed to prevent dictionary attacks, which introduces a 5-second delay during session setup, can be bypassed through the use of asynchronous requests. This bypass negates the intended anti-brute-force protection, potentially allowing attackers to conduct dictionary attacks more efficiently against user credentials or other authentication mechanisms.","epss":{"date":"2026-11-08","percentile":0.42668,"score":0.00494},"exploits":[],"kev":null,"metrics":[{"score":3.7,"severity":"low","source":"CNA: redhat","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"}],"modifiedAt":1794193662590,"publishedAt":1753994642968,"references":[{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2023-32251"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2385852"},{"source":"CNA: redhat","tags":[],"url":"https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=b096d97f47326b1e2dbdef1c91fab69ffda54d17"},{"source":"CNA: redhat","tags":[],"url":"https://www.zerodayinitiative.com/advisories/ZDI-23-699/"}],"remediation":[],"revision":"fe1e21a560cfeac33654cfba46dd4efb0ccbe4a6fcdc057b8316c84e07b358cc","sources":[{"modifiedAt":1794193662590,"name":"CNA: redhat","retrievedAt":1794197298296,"url":"https://www.cve.org/CVERecord?id=CVE-2023-32251"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1794197312066,"url":"https://api.first.org/data/v1/epss?cve=CVE-2023-32251"}],"ssvc":{"assessedAt":1754054982668,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Kernel: ksmbd brute force delay bypass via asynchronous requests","updatedAt":1794197312066}
