Published severityHighOperational priority:Medium, lowered one band.downgradedsince 30 Jan 2025

Evidence used

  • No CISA KEV confirmation is currently recorded.
  • Exploitation requires an existing local or physical foothold with privileges.
  • EPSS is 0.81% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict local access and enforce least privilege on affected hosts.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs Flexera FlexNet Publisher and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: As exposure requiresRemediation target: Within 365 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

What, why and how

A misconfiguration in lmadmin.exe of FlexNet Publisher versions prior to 2024 R1 (11.19.6.0) allows the OpenSSL configuration file to load from a non-existent directory. An unauthorized, locally authenticated user with low privileges can potentially create the directory and load a specially crafted openssl.conf file leading to the execution of a malicious DLL (Dynamic-Link Library) with elevated privileges.

What

A misconfiguration in lmadmin.exe of FlexNet Publisher versions prior to 2024 R1 (11.19.6.0) allows the OpenSSL configuration file to load from a non-existent directory. An unauthorized, locally authenticated user with low privileges can potentially create the directory and load a specially crafted openssl.conf file leading to the execution of a malicious DLL (Dynamic-Link Library) with elevated privileges.

Why

The product uses a fixed or controlled search path to find resources, but one or more locations in that path can be under the control of unintended actors.

How

An attacker operating through local access may attempt exploitation with low privileges. If successful, the issue may gain additional privileges.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

CWE-427: Uncontrolled Search Path Element. The product uses a fixed or controlled search path to find resources, but one or more locations in that path can be under the control of unintended actors.
