EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
Description
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.
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of the affected component has shipped for CVE-2024-5443 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2024-5443 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2024-5443. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2024-5443 in your dependencies?
O3 detects CVE-2024-5443 across dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
