CVE-2026-76452 Cisco CVE debrief

Who should care

Defenders responsible for Cisco License On-Prem systems, especially those with administrative access to the web-based management interface, should assess exposure and potential impacts on confidentiality.

Why it matters

This vulnerability allows an authenticated, remote attacker to conduct SQL injection attacks, potentially impacting system confidentiality. Defenders should prioritize verifying exposure and assessing potential impacts, especially for administrative users with access to the web-based management interface.

• Potential unauthorized access to sensitive information in the internal database.
• Possible impact on system confidentiality due to exploitation.

Technical summary

The vulnerability exists in the web-based management interface of Cisco License On-Prem, formerly Cisco Smart Software Manager On-Prem (SSM On-Prem), due to insufficient validation of user-supplied input. An authenticated, remote attacker could exploit this vulnerability by sending a crafted request to the web-based management interface, potentially allowing access to additional contents of the internal database that should not be accessible to administrative users, thus impacting system confidentiality. This could allow the attacker to read additional contents of the internal database of an affected application that should not normally be accessible to administrative users.

Defensive priority

Defenders should prioritize verifying exposure and assessing potential impacts on confidentiality, especially for administrative users with access to the web-based management interface.

Recommended defensive actions

• Verify exposure by checking affected Cisco License On-Prem versions and ensuring administrative users have only necessary access to the web-based management interface.
• Assess potential impacts on confidentiality and implement compensating controls to limit access to sensitive information.
• Monitor for suspicious activity and implement logging and auditing to detect potential exploitation attempts.
• Review and apply vendor patch guidance for Cisco License On-Prem.
• Conduct an exposure review to identify potentially vulnerable systems.
• Implement monitoring to detect potential exploitation attempts.
• Maintain an asset inventory to track Cisco License On-Prem systems.
