Impact

The vulnerability in Cisco Identity Services Engine stems from the improper validation of user-supplied input, enabling an authenticated remote attacker with low‑privileged administrative credentials to conduct SQL injection attacks. A successful exploit allows the attacker to read or modify data in the underlying database, potentially compromising confidential system information and altering critical configuration data.

Affected Systems

Cisco Identity Services Engine Software is affected by this vulnerability. No specific product versions are listed in the advisory, so any installation of this software may need to be evaluated for the presence of the flaw.

Risk and Exploitability

The CVSS score of 7.1 indicates a high severity, but the EPSS score of less than 1% suggests that the likelihood of exploitation in the wild is currently low. The flaw requires authenticated access, so it is not publicly exploitable; it is not listed in the CISA KEV catalog.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply the vendor‑released patch or upgrade Cisco Identity Services Engine to a version that addresses the SQL injection flaw.
  • Enforce strict least‑privilege policies so that only the minimal number of administrators have low‑privileged access needed for day‑to‑day operations.
  • Implement input validation or parameterized queries to prevent malicious SQL payloads from reaching the database.
  • Continuously monitor database logs for anomalous queries or access attempts that may indicate an ongoing attack.
