Remote Code Execution in Cisco Smart Software Manager On-Prem

CVE-2026-20160

What is CVE-2026-20160?

CVE-2026-20160 is a critical vulnerability affecting the Cisco Smart Software Manager On-Prem (SSM On-Prem), which is a platform utilized by organizations for managing software licenses and entitlements in a centralized manner. This vulnerability permits an unauthenticated remote attacker to execute arbitrary commands on the underlying operating system of the SSM On-Prem host due to the unintended exposure of an internal service. By sending specially crafted requests to the vulnerable API, an attacker can gain root-level privileges, thus enabling extensive control over the system. This exploitation poses significant risks to organizations, as it can lead to unauthorized access, data manipulation, and potential system-wide damage.

Potential impact of CVE-2026-20160

1. Remote Code Execution: The core issue allows attackers to execute arbitrary commands with root-level access. This capability can be leveraged to manipulate system configurations, access sensitive data, and deploy malicious software, potentially leading to widespread compromise of organizational assets.

2. Loss of Confidentiality and Integrity: Successful exploitation can result in unauthorized access to sensitive information, including licenses and other proprietary data. Attackers can alter, delete, or exfiltrate such data, undermining the integrity and confidentiality vital for organizational operations.

3. Operational Disruption: Given the critical role of SSM On-Prem in managing software compliance and licensing, exploitation of this vulnerability can disrupt operations significantly. This can lead to increased downtime, resource allocation for incident response, and potential loss of revenue due to service unavailability.
