parisneo/lollms-webui: Path Traversal: '..filename'
CVE-2024-4322 is a high-severity path traversal: '..filename' vulnerability in parisneo/lollms-webui from ParisNeo, with a CVSS 3.0 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected parisneo/lollms-webui versions: latest and earlier. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 30.8% chance of exploitation within 30 days, which is in the top 1.72% of all scored CVEs.
EPSS places it among the vulnerabilities most likely to be exploited soon.
What to do
- Update Lollms Web UI to 9.8 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
A path traversal vulnerability exists in the parisneo/lollms-webui application, specifically within the `/list_personalities` endpoint. By manipulating the `category` parameter, an attacker can traverse the directory structure and list any directory on the system. This issue affects the latest version of the application. The vulnerability is due to improper handling of user-supplied input in the `list_personalities` function, where the `category` parameter can be controlled to specify arbitrary directories for listing. Successful exploitation of this vulnerability could allow an attacker to list all folders in the drive on the system, potentially leading to information disclosure.

The underlying weakness: Path Traversal: '..filename'
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize '..filename' (leading backslash dot dot) sequences that can resolve to a location that is outside of that directory.
How developers prevent this class of flaw
- Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174). Such errors could be used to bypass allowlist validation schemes by introducing dangerous inputs after they have been checked.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: poc, automatable: no, technical impact: partial).
- Record last changed materially (score, affected products, status or references).
