CVE-2025-12418: Potential Denial of Service in Supported Versions of Revenera InstallShield

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.16% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No special conditions are required; it is repeatable.
  • Fixed version: Revenera InstallShield InstallShield2023R2-CVE-2025-12418-SecurityPatch, InstallShield2024R2-CVE-2025-12418-SecurityPatch.

Low priority for now. Upgrade to Revenera InstallShield InstallShield2023R2-CVE-2025-12418-SecurityPatch, InstallShield2024R2-CVE-2025-12418-SecurityPatch or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

Potential Denial of Service issue in all supported versions of Revenera InstallShield version 2025 R1, 2024 R2, 2023 R2, and prior. When e.g., a local administrator performs an uninstall, a symlink may get followed on removal of a user writeable configuration directory and induce a Denial of Service as a result. The issue is resolved through the hotfixes InstallShield2025R1-CVE-2025-12418-SecurityPatch, InstallShield2024R2-CVE-2025-12418-SecurityPatch, and InstallShield2023R2-CVE-2025-12418-SecurityPatch.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

EPSS, last 120 days

FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

No commit or PR link among the references.

Credits

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
