In the ever-evolving landscape of cybersecurity, staying ahead of potential threats is paramount. Recently, Dell Technologies issued a critical security update, DSA-2024-323, addressing an Incorrect Privilege Assignment vulnerability in Dell Power Manager. This vulnerability, identified as CVE-2024-39576, poses significant risks, including potential code execution and elevation of privileges by low-privileged attackers with local access. This article delves into the details of the vulnerability, its impact, and provides actionable advice to mitigate such threats in the future.
Detailed Analysis
Impact and Severity
The vulnerability in Dell Power Manager, versions 3.15.0 and prior, has been classified as high impact with a CVSS base score of 8.8. This score reflects the severity of the potential exploitation, which could allow attackers to execute arbitrary code and gain elevated privileges on the affected system. The vulnerability arises from an incorrect privilege assignment, which can be exploited by attackers with local access to the system.
Technical Details
The vulnerability, CVE-2024-39576, is rooted in the way Dell Power Manager assigns privileges to users. A low-privileged attacker can exploit this flaw to execute code with higher privileges, potentially leading to a full system compromise. The vulnerability does not require user interaction, making it particularly dangerous in environments where physical access to systems is possible
Affected Products and Remediation
Dell Power Manager versions prior to 3.16.0 are affected by this vulnerability. Dell has released an updated version, 3.16.0, which addresses the issue. Users are strongly advised to update to the latest version to mitigate the risk of exploitation
Workarounds and Mitigations
Currently, there are no workarounds or mitigations available for this vulnerability. The only effective measure is to apply the security update provided by Dell
