Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: A critical flaw in VMware Enhanced Authentication Plug-in (EAP). π **Consequences**: Allows **Arbitrary Authentication Relay** and **Session Hijacking**.β¦
π **Attacker Capabilities**: Can hijack sessions and relay service tickets. π **Impact**: High impact on Confidentiality, Integrity, and Availability (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H).β¦
β οΈ **Exploitation Threshold**: **Low** network access, **Low** complexity, but requires **User Interaction** (UI:R). Attackers must trick a target domain user into requesting/relaying tickets via a web browser.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Public Exploit**: **No** public PoC or wild exploitation data available in the provided records. However, the CVSS score suggests it is highly dangerous if exploited.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for the presence of **VMware Enhanced Authentication Plug-in** in Horizon clients. Check for unpatched versions listed in VMSA-2024-0003. Monitor for unusual authentication relay activities.
Q8Is it fixed officially? (Patch/Mitigation)
β **Official Fix**: Yes. VMware released **VMSA-2024-0003** on Feb 20, 2024. Users should update to the patched version immediately to close the authentication relay hole.
Q9What if no patch? (Workaround)
π§ **No Patch Workaround**: Disable the Enhanced Authentication Plug-in if not strictly necessary. Implement strict network segmentation and monitor for Kerberos relay attacks.β¦
π₯ **Urgency**: **CRITICAL**. With CVSS High severity and no auth required for network access, this is a high-priority fix. Immediate patching via VMSA-2024-0003 is strongly recommended.
