Directory Traversal Affecting firefox package, versions *
Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

CVE-2024-29180 (opens in a new tab)How to fix?
There is no fixed version for RHEL:6 firefox.
NVD Description
Note: Versions mentioned in the description apply only to the upstream firefox package and not the firefox package as distributed by RHEL.
See How to fix? for RHEL:6 relevant fixed versions and status.
Prior to versions 7.1.0, 6.1.2, and 5.3.4, the webpack-dev-middleware development middleware for devpack does not validate the supplied URL address sufficiently before returning the local file. It is possible to access any file on the developer's machine. The middleware can either work with the physical filesystem when reading the files or it can use a virtualized in-memory memfs filesystem. If writeToDisk configuration option is set to true, the physical filesystem is used. The getFilenameFromUrl method is used to parse URL and build the local file path. The public path prefix is stripped from the URL, and the unsecaped path suffix is appended to the outputPath. As the URL is not unescaped and normalized automatically before calling the midlleware, it is possible to use %2e and %2f sequences to perform path traversal attack.
Developers using webpack-dev-server or webpack-dev-middleware are affected by the issue. When the project is started, an attacker might access any file on the developer's machine and exfiltrate the content. If the development server is listening on a public IP address (or 0.0.0.0), an attacker on the local network can access the local files without any interaction from the victim (direct connection to the port). If the server allows access from third-party domains, an attacker can send a malicious link to the victim. When visited, the client side script can connect to the local server and exfiltrate the local files. Starting with fixed versions 7.1.0, 6.1.2, and 5.3.4, the URL is unescaped and normalized before any further processing.
