Detailsinfo

A vulnerability was found in Sage Employee Self Service (affected version not known). It has been rated as problematic. This issue affects some unknown functionality of the component Custom Logo Functionality. The manipulation with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-22. 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. Impacted is confidentiality. The summary by CVE is:

A path traversal vulnerability exists in Sage Employee Self Service’s custom logo functionality due to improper validation of file path parameters. By leveraging directory traversal sequences and their encoded variants, an attacker may bypass directory restrictions and access files outside the application's intended file system scope. Successful exploitation would require knowledge of valid file names and paths. Depending on the privileges of the affected component, exploitation could result in the disclosure of sensitive information, including configuration files, environment settings, application assets, and log data. The vulnerability has been remediated through enhanced path validation and secure path resolution controls that prevent access to unauthorised locations.
