Dell Repository Manager (DRM): Improper Limitation of a Pathname to a Restricted Directory
CVE-2024-28976 is a high-severity improper limitation of a pathname to a restricted directory vulnerability in Dell Repository Manager (DRM) from Dell, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists version 3.4.5 as the first without the flaw, so updating Dell Repository Manager (DRM) to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.24% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Dell Repository Manager (DRM) to 3.4.5 or a later version.
- Update repository_manager to 3.4.5 or a later version.
- Read the advisory on dell.com for workarounds and exact fixed builds.

Official description
Dell Repository Manager, versions prior to 3.4.5, contains a Path Traversal vulnerability in API module. A local attacker with low privileges could potentially exploit this vulnerability to gain unauthorized write access to the files stored on the server filesystem with the privileges of the running web application.

The underlying weakness: Improper Limitation of a Pathname to a Restricted Directory
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
How developers prevent this class of flaw
- For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth.
