Summary

CVE-2024-5443 is a critical-severity Path Traversal: '\..\filename' (CWE-29) vulnerability. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 36% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

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 Data

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.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

Input validation directly neutralizes the '\..\filename' sequence before pathname resolution occurs.

AC-3 Access Enforcement partial match

Access enforcement denies requests that resolve outside the intended directory even when the traversal sequence is present.

Secure architecture principles include directory sandboxing and safe file-access design that mitigate path traversal.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly require neutralizing path traversal sequences such as '\..\filename'.
