Security readout for executives and security teams

Plain-English summary

CVE-2021-27695 is a stored cross-site scripting issue in openMAINT 2.1-3.3-b. An attacker can save malicious script or HTML in “Add” section fields such as Name and Code. When another user views affected records, the script may run in that user’s browser.

Executive priority

Treat as a medium-priority application security issue. It is not listed as actively exploited in the provided sources, but stored XSS can affect privileged users and operational data workflows. Prioritize if openMAINT is externally reachable or used by many non-administrative users.

Technical view

The CVE describes multiple stored XSS flaws in openMAINT 2.1-3.3-b affecting input in Add sections, including Add Card Building and Floor, through Name and Code parameters. No CVSS score, CWE, vendor advisory, or fixed version is included in the provided sources. Exploit-DB has a public entry for this CVE.

Likely exposure

Organizations running openMAINT 2.1-3.3-b are potentially exposed, especially if untrusted or low-privileged users can create records. Exposure is higher where openMAINT is internet-accessible or broadly available to contractors, tenants, or operational staff.

Exploitation context

The source bundle includes an Exploit-DB reference, indicating public exploit information exists. The sources do not show CISA KEV listing or confirmed active exploitation. Successful impact likely depends on an attacker’s ability to submit data into affected Add sections and lure or wait for another user to view it.

Researcher notes

Evidence is limited to the CVE description and Exploit-DB reference. The affected range is stated as openMAINT 2.1-3.3-b. No official patch, CVSS vector, authentication requirement, or exact role requirement is provided. Avoid assuming broader openMAINT versions are affected without vendor confirmation.

Mitigation direction

  • Identify whether openMAINT 2.1-3.3-b is deployed.
  • Check official openMAINT or maintainer guidance for fixed versions or patches.
  • Restrict access to openMAINT to trusted networks and users.
  • Limit record-creation permissions to users who need them.
  • Review stored Name and Code fields for suspicious script-like content.

Validation and detection

  • Inventory openMAINT versions and exposed access paths.
  • Confirm whether untrusted users can access Add sections.
  • Review application logs for unusual record creation activity.
  • Inspect recently created Building, Floor, and similar records.
  • Verify remediation against vendor guidance when available.
