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 · unedited
A vulnerability in the file system of Cisco Elastic Services Controllers could allow an authenticated, local attacker to gain access to sensitive user credentials that are stored in an affected system. More Information: CSCvd73677. Known Affected Releases: 2.3(2).

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 · moderate confidence

A local file system vulnerability in Cisco Elastic Services Controllers allows an authenticated local attacker to access sensitive user credentials stored on the system. The attacker exploits improper file permission or storage handling of authentication data in the affected software version 2.3(2).

MitigationApply the vendor patch from Cisco (CSCvd73677) when available; restrict local system access to trusted administrators and verify proper file permissions on credential storage locations.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify Cisco Elastic Services Controller version
    Use the system's command interface or administrative interface to query the installed software version of Cisco Elastic Services Controller
    Affected if The installed version is exactly 2.3(2)
  2. Verify local user access exposure
    Determine whether untrusted or low-privilege local users have access to the system shell or CLI
    Affected if Untrusted local users can access the system and credentials are stored on the same file system
  3. Inspect credential file permissions
    Locate and examine file permissions on authentication data storage locations using standard file system inspection commands (ls -la)
    Affected if Credentials are stored in files readable by non-privileged local users due to overly permissive file modes

The environment is affected only if Cisco Elastic Services Controller version 2.3(2) is installed and local untrusted users can access credential storage files on the system.
