A score above 50% indicates significantly elevated exploitation risk — immediate patching is strongly recommended.

Is CVE-2017-17562 in the CISA Known Exploited Vulnerabilities catalog?

Yes. CVE-2017-17562 (Embedthis GoAhead Remote Code Execution Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2021-12-10. CISA required all US federal civilian agencies to remediate this vulnerability by 2022-06-10. The required action was: Apply updates per vendor instructions. Being listed in the KEV catalog is the strongest possible confirmation of active exploitation — treat this as a critical priority.

Which products and versions are affected by CVE-2017-17562?

CVE-2017-17562 affects embedthis goahead; oracle integrated lights out manager (2 versions, e.g. 3.0, 4.0). Check the affected-products list on this page against your deployed version to confirm exposure.

Is there exploit tooling available for CVE-2017-17562?

A Nuclei detection template exists for CVE-2017-17562, 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-2017-17562 published, and has it been updated?

CVE-2017-17562 was published on December 12, 2017 and was last updated on April 21, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

EPSS Exploitation Probability

94.3%probability of exploitation in next 30 days

Very High Risk100th percentile0.00%

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

Embedthis GoAhead before 3.6.5 allows remote code execution if CGI is enabled and a CGI program is dynamically linked. This is a result of initializing the environment of forked CGI scripts using untrusted HTTP request parameters in the cgiHandler function in cgi.c. When combined with the glibc dynamic linker, this behaviour can be abused for remote code execution using special parameter names such as LD_PRELOAD. An attacker can POST their shared object payload in the body of the request, and reference it using /proc/self/fd/0.
