CVE-2020-27125: Cisco Security Manager Static Credential Vulnerability

A vulnerability in Cisco Security Manager could allow an unauthenticated, remote attacker to access sensitive information on an affected system. The vulnerability is due to insufficient protection of static credentials in the affected software. An attacker could exploit this vulnerability by viewing source code. A successful exploit could allow the attacker to view static credentials, which the attacker could use to carry out further attacks.

Security readout for executives and security teams

Plain-English summary

CVE-2020-27125 is a Cisco Security Manager flaw where static credentials were not sufficiently protected. A remote unauthenticated attacker could view source code, obtain those credentials, and use them for follow-on attacks. The main business risk is credential exposure leading to broader compromise of security management infrastructure.

Executive priority

Treat as high priority where Cisco Security Manager is deployed, especially if reachable beyond trusted administrative networks. The issue can expose credentials on a security management system, creating risk beyond the application itself. If the product is not present, business exposure is unlikely.

Technical view

The CVE describes insufficient protection of static credentials in Cisco Security Manager. The attack vector is network-accessible, requires no authentication or user interaction, and has high confidentiality and integrity impact with no availability impact. The published CVSS v3.1 score is 7.4, with high attack complexity.

Likely exposure

Exposure is limited to organizations running affected Cisco Security Manager deployments. The bundle does not identify exact affected versions, so teams should compare their deployment against Cisco’s advisory and inventory any reachable Cisco Security Manager instances.

Exploitation context

The provided sources do not show CISA KEV listing or confirmed active exploitation. The CVE states exploitation could occur by viewing source code to reveal static credentials, which could then enable further attacks. No exploit procedure or public weaponization evidence is provided in the bundle.

Researcher notes

The bundle gives strong high-level impact detail but omits exact affected versions and specific fixes. CVSS indicates AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N. CWE is listed as CWE-20, though the described weakness is static credential exposure. Validate against Cisco’s advisory before assigning scope.

Mitigation direction

  • Review Cisco’s advisory for affected releases and vendor remediation guidance.
  • Identify all Cisco Security Manager deployments and ownership.
  • Limit untrusted network access while remediation is assessed.
  • Review exposed credentials per Cisco guidance and incident response policy.
  • Prioritize remediation for internet-facing or broadly reachable systems.

Validation and detection

  • Confirm whether Cisco Security Manager is deployed in the environment.
  • Compare installed release details with Cisco’s advisory.
  • Check whether management interfaces are reachable from untrusted networks.
  • Review logs for unusual access to Cisco Security Manager resources.
  • Look for suspicious use of credentials associated with the platform.
