This vulnerability allows a malicious actor with unprivileged local access to a Windows operating system to hijack a privileged EAP session when initiated by a privileged domain user on the same system. The high CVSS score of 7.8 indicates a significant security risk, especially considering the potential for unauthorized access to sensitive information.
Risk to organizations includes compromised data integrity and confidentiality, leading to potential data breaches and loss of trust from users. Given the nature of the vulnerability and the potential impacts, organizations should prioritize patching immediately.
As of now, there is no known exploit or public proof of concept for this vulnerability, but the exploitability score suggests a high potential for exploitation. Therefore, immediate attention is required to mitigate the associated risks.
Organizations should assess their environments for this vulnerability and ensure that proper remediation is in place to prevent any potential exploitation.
Vulnerability Details
The session hijack vulnerability in the Deprecated VMware Enhanced Authentication Plug-in is attributed to insufficient session management. The CVSS version 3.1 vector indicates a local attack vector, high attack complexity, and low privileges required, confirming that an unprivileged user can exploit this vulnerability.
Affected systems are those running the Deprecated VMware Enhanced Authentication Plug-in, which is now considered obsolete. The vulnerability is classified under CWE-384, indicating a session fixation issue.
Technical Analysis
The root cause of this vulnerability stems from a failure to properly manage EAP session tokens, allowing an unprivileged user to hijack an active session of a privileged user. The attack vector is local, meaning the attacker must have physical or remote access to the same network as the victim.
The attack complexity is rated as high, as the attacker must possess a certain level of access to initiate the hijacking process. Privileges required are low, meaning that anyone with basic access can potentially exploit this vulnerability.
User interaction is not required, which increases the risk as this vulnerability can be exploited without the victim's knowledge. The impacts are severe, with high confidentiality, integrity, and availability impacts, indicating that sensitive data could be compromised or destroyed.
Risk & Impact Analysis
Real-world deployment of this vulnerability presents a considerable risk for organizations using the Deprecated VMware Enhanced Authentication Plug-in. The potential for attackers to hijack privileged sessions poses a significant threat to data confidentiality and integrity.
Organizations should consider the blast radius of this vulnerability. If exploited, an attacker could gain unauthorized access to sensitive systems and data, leading to severe operational and reputational damage.
Given the high CVSS score of 7.8, the urgency for remediation is critical. Organizations should prioritize patching immediately to mitigate this vulnerability and reduce the risk of exploitation.
