What is GHSA-RPX7-33J2-XX9X?

GHSA-RPX7-33J2-XX9X is a low-severity security vulnerability in nemo_toolkit (pip), affecting versions < 1.6.0. It is fixed in 1.6.0.

How severe is GHSA-RPX7-33J2-XX9X?

GHSA-RPX7-33J2-XX9X has a CVSS score of 2.0 (Low). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.

Which versions of nemo_toolkit are affected by GHSA-RPX7-33J2-XX9X?

nemo_toolkit (pip) versions < 1.6.0 is affected.

Is there a fix for GHSA-RPX7-33J2-XX9X?

Yes. GHSA-RPX7-33J2-XX9X is fixed in 1.6.0. Upgrade to this version or later.

Is GHSA-RPX7-33J2-XX9X exploitable, and should I be worried?

Whether GHSA-RPX7-33J2-XX9X is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

What actually determines whether GHSA-RPX7-33J2-XX9X is exploitable, and how bad it is?

Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.

How do I fix GHSA-RPX7-33J2-XX9X?

Upgrade nemo_toolkit to 1.6.0 or later.

Summary

Arbitrary file deletion in NeMo ASR webapp

Description

NVIDIA NeMo contains a vulnerability in ASR WebApp, where Relative Path Traversal (CWE-23) may lead to deletion of any directory through the "../" structure when admin privileges are available.

CVSS Score = 2.0
https://nvd.nist.gov/vuln-metrics/cvss/v3-calculator?vector=AV:L/AC:L/PR:H/UI:R/S:U/C:N/I:L/A:N

Workarounds

The changes in commit https://github.com/NVIDIA/NeMo/commit/f7e4ed7e4f7f2fa43765a38c2fafa1b6d1ebd7c0 can be applied to any version of the web app without any adverse effect.

Additional Information

Exploit Found on: 2021.12.16
Exploit Found by: @haby0

Impact

When the optional tool ASR Webapp (https://github.com/NVIDIA/NeMo/tree/main/tools/asr_webapp) is used prior to commit https://github.com/NVIDIA/NeMo/commit/f7e4ed7e4f7f2fa43765a38c2fafa1b6d1ebd7c0, some interfaces do not verify user input. Malicious attackers can construct malicious requests to delete any directory through the "../" structure.

The vulnerability affects only cases where this particular web app is started by a user with superuser permissions. The web application is not a part of the regular pip release or the corresponding container, and impacts only users that clone the repository in its entirety and execute the web app (while also possessing superuser permissions).

GHSA-RPX7-33J2-XX9X has a CVSS score of 2.0 (Low). The vector is requires local access, high privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (1.6.0); upgrading removes the vulnerable code path.

Affected versions

nemo_toolkit (< 1.6.0)

Security releases

nemo_toolkit → 1.6.0 (pip)

Kodem intelligence

Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.

Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Remediation advice

This vulnerability has been patched via https://github.com/NVIDIA/NeMo/commit/f7e4ed7e4f7f2fa43765a38c2fafa1b6d1ebd7c0, which is effectively any clone of the repository post r1.5.1 branch. Since the web app is not distributed via pip release or container, users who clone the main branch post this commit will possess the patch.
