CVE-2024-5443
Published: 22 June 2024
Summary
CVE-2024-5443 is a critical-severity Path Traversal: '\..\filename' (CWE-29) vulnerability. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 4.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
CVE-2024-5443 is a path traversal vulnerability in the parisneo/lollms software, specifically in the ExtensionBuilder().build_extension() function exposed via the /mount_extension endpoint. The flaw stems from inadequate sanitization of the data.category and data.folder parameters, which accept empty strings and allow construction of a package_path that resolves to the filesystem root. This affects all versions through 5.9.0 and is assigned CWE-29 with a CVSS score of 9.8.
An unauthenticated remote attacker who can place a config.yaml file in a controllable location can append that path to the extensions list, causing the application to execute an __init__.py file in the current directory and achieve remote code execution.
The vulnerability was fixed in version 9.8; the referenced commits on GitHub and the huntr.com bounty entries document the remediation that prevents empty category or folder values from producing a root-level package_path.
The EPSS score has remained flat at 0.1747 with no material increase after disclosure.

Vulnerability details
CVE-2024-4320 describes a vulnerability in the parisneo/lollms software, specifically within the `ExtensionBuilder().build_extension()` function. The vulnerability arises from the `/mount_extension` endpoint, where a path traversal issue allows attackers to navigate beyond the intended directory structure. This is facilitated by the `data.category`…

and `data.folder` parameters accepting empty strings (`""`), which, due to inadequate input sanitization, can lead to the construction of a `package_path` that points to the root directory. Consequently, if an attacker can create a `config.yaml` file in a controllable path, this path can be appended to the `extensions` list and trigger the execution of `__init__.py` in the current directory, leading to remote code execution. The vulnerability affects versions up to 5.9.0, and has been addressed in version 9.8.
