CVE-2025-68421 Comarch CVE debrief

CVE-2025-68421 involves a Comarch ERP Optima client using a hard-coded database user password that cannot be changed. This allows remote attackers to access the database with elevated privileges, including executing system commands on the server. The issue was fixed in version 2026.4. Defenders managing Comarch ERP Optima installations, especially those with remote database access, should assess their exposure and prioritize verification and remediation efforts. Evidence is limited to CVE and NVD records.

Who should care

Defenders managing Comarch ERP Optima installations, especially those with remote database access, should assess their exposure and prioritize verification and remediation efforts.

Why it matters

CVE-2025-68421 involves a hard-coded database user password in Comarch ERP Optima, allowing remote attackers to access the database with elevated privileges and execute system commands. Defenders should verify exposure, especially in environments with remote database access, and prioritize upgrades or compensating controls. Evidence is limited to CVE and NVD records.

  • Remote attackers could gain elevated access to the database.
  • System commands could be executed on the server.
  • Database security may be compromised.
  • Verification of exposure and remediation is necessary.

Technical summary

The Comarch ERP Optima client utilizes a hard-coded password for a database user, which cannot be altered. This insecure practice allows remote attackers to gain elevated access to the database, potentially leading to system command execution on the server. The vulnerability was addressed in version 2026.4 of the software. Defenders should prioritize verifying exposure of Comarch ERP Optima installations, especially in environments where remote access to the database is possible, and assess the feasibility of immediate upgrades to version 2026.4 or application of compensating controls.

Defensive priority

Defenders should prioritize verifying exposure of Comarch ERP Optima installations, especially in environments where remote access to the database is possible, and assess the feasibility of immediate upgrades to version 2026.4 or application of compensating controls.

Recommended defensive actions

  • Verify Comarch ERP Optima installations for exposure, especially in environments with remote database access.
  • Assess the feasibility of upgrading to version 2026.4.
  • Implement compensating controls to limit database access.
  • Monitor for potential exploitation attempts.
  • Review relevant monitoring, detection, and logs for exposed assets that need extra review.
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented.
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.

Evidence notes

The CVE record and NVD entry provide details about the hard-coded password issue in Comarch ERP Optima and its potential impact. However, specific details about affected versions, beyond the fix in version 2026.4, and exploitation are limited.
