CVE-2021-1363
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedMultiple vulnerabilities in the web-based management interface of Cisco Unified Communications Manager IM & Presence Service could allow an authenticated, remote attacker to conduct SQL injection attacks on an affected system. These vulnerabilities are due to improper validation of user-submitted parameters. An attacker could exploit these vulnerabilities by authenticating to the application and sending malicious requests to an affected system. A successful exploit could allow the attacker to obtain data or modify data that is stored in the underlying database.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceMultiple SQL injection vulnerabilities exist in the web-based management interface of Cisco Unified Communications Manager IM & Presence Service due to improper validation of user-submitted parameters. An authenticated attacker can send malicious requests containing unsanitized SQL input to obtain or modify data in the underlying database.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed CUCM IM&P versionLog into the Cisco Unified Communications Manager administrative interface and navigate to System > Version, or run the 'show version' command via CLI on the IM&P serverAffected if The displayed version falls within 10.5 to 11.5(1)su9 (exclusive of 11.5(1)su9) OR 12.0 to 12.5(1)su4 (exclusive of 12.5(1)su4)
-
Confirm web-based management interface is enabledAccess the Cisco IM&P Administration portal at the standard HTTPS port (commonly 8443) or check via CLI with 'show network eth0' to identify the management IP and verify the web service is runningAffected if The web-based management interface is accessible and operational on the target system
-
Verify authentication method for management portalAttempt to access the IM&P web management login page or review the authentication configuration under Cisco Unified Communications Manager > User Management > LDAPAffected if The management interface uses local database authentication rather than external LDAP with parameterized query enforcement enabled
The environment is affected if the installed CUCM IM&P version is within the vulnerable ranges (10.5 <= version < 11.5(1)su9 OR 12.0 <= version < 12.5(1)su4) AND the web-based management interface is enabled and uses local database authentication.
