Dell SupportAssist for Home PCs versions 4.6.1 and prior and Dell SupportAssist for Business PCs versions 4.5.0 and prior, contain a symbolic link (symlink) attack vulnerability in the software remediation component. A low-privileged authenticated user could potentially exploit this vulnerability, gaining privileges escalation, leading to arbitrary deletion of files and folders from the system. This vulnerability is classified as high severity due to its potential impact on system integrity and availability. The CVSS score of 7.1 indicates a high severity level, with specific metrics showing a local attack vector and low attack complexity. Attackers may leverage this vulnerability to escalate their privileges and cause significant damage.
Risk to organizations includes unauthorized access to sensitive files and the potential for data loss. As such, organizations should prioritize patching immediately to address this vulnerability and protect their systems from exploitation.
Currently, there are no known exploits or public proof of concept available for CVE-2024-52535, but the nature of the vulnerability necessitates immediate attention from security teams to mitigate any potential risks.
Organizations using affected versions of Dell SupportAssist should monitor for any unusual activity and ensure that they are prepared to implement the necessary patches once available.
Vulnerability Details
The vulnerability allows for privilege escalation through symbolic link attacks, specifically affecting Dell SupportAssist for Home PCs versions 4.6.1 and prior and Dell SupportAssist for Business PCs versions 4.5.0 and prior. The CVSS score of 7.1 reflects the high potential impact on affected systems, with both integrity and availability being classified as high impact. The vulnerability was published on December 25, 2024, and is tracked under CWE-59 and CWE-61 classifications.
Technical Analysis
The root cause of this vulnerability stems from improper handling of symbolic links within the remediation component of the software, allowing low-privileged authenticated users to bypass intended access controls. The attack vector is local, meaning that an attacker must have some level of access to the system to exploit the vulnerability, and the complexity is low as it does not require significant technical skills or user interaction.
The potential impacts of exploitation include unauthorized access to confidential files, leading to data integrity and availability issues. Given that both integrity and availability impacts are rated high, the urgency for remediation cannot be overstated.
Risk & Impact Analysis
Real-world deployment of this vulnerability poses a significant risk to organizations, particularly those using Dell SupportAssist for Business and Home PCs. The ability for low-privileged users to escalate their privileges can lead to unauthorized data deletion, resulting in operational disruptions and potential data loss. The blast radius of this vulnerability could extend beyond individual systems, affecting network stability and user trust.
Organizations should address this vulnerability in their priority patch cycle, given the high CVSS score and potential for exploitation. The EPS score of 0.00472 places this vulnerability in a low-risk category for immediate exploitation, but the nature of the vulnerability warrants proactive measures.
