How do I detect CVE-2021-30497 in my code and dependencies?

Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).

How do I mitigate CVE-2021-30497 if there is no patch (or I can't update yet)?

Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.

Is CVE-2021-30497 actively exploited in the wild?

Yes. There are 1 known exploit references for CVE-2021-30497, including 1 in-the-wild exploitation observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2021-30497?

CVE-2021-30497 has an EPSS (Exploit Prediction Scoring System) score of 96.6%, placing it in the 100th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. A score above 50% indicates significantly elevated exploitation risk — immediate patching is strongly recommended.

What type of vulnerability is CVE-2021-30497?

CVE-2021-30497 is classified as Path Traversal (CWE-22). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

Is there exploit tooling available for CVE-2021-30497?

A Nuclei detection template exists for CVE-2021-30497, meaning automated scanners can fingerprint it. Public exploit tooling significantly increases real-world risk — prioritize patching and ensure detection coverage. Exploit tooling should only ever be used in isolated, authorized testing environments.

When was CVE-2021-30497 published, and has it been updated?

CVE-2021-30497 was published on April 6, 2022 and was last updated on August 3, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Ivanti Avalanche (Premise) 6.3.2 allows remote unauthenticated users to read arbitrary files via Absolute Path Traversal. The imageFilePath parameter processed by the /AvalancheWeb/image endpoint is not verified to be within the scope of the image folder, e.g., the attacker can obtain sensitive information via the C:/Windows/system32/config/system.sav value.
