A critical vulnerability in the web-based management interface of Cisco Smart Software Manager On-Prem (CVE-2022-20939) has been discovered, which could potentially allow an authenticated, remote attacker to elevate privileges on an affected system. This privilege escalation vulnerability has been found to be caused by inadequate protection of sensitive user data. The following article will detail the exploit, code snippets, links to original references, and recommendations for addressing this security flaw.

Exploit

The exploit takes advantage of insufficient protection of sensitive user information within the web-based management interface of Cisco Smart Software Manager On-Prem. An attacker could access specific logs on the affected system and utilize the obtained information to elevate privileges to System Admin. This can lead to unauthorized tampering, theft of sensitive data, and potential misuse of critical system resources.

Code Snippet

While there is no specific code snippet available to demonstrate the exploit, a potential attacker would be looking for certain log files within the web-based management interface of the Cisco Smart Software Manager On-Prem system.

For instance

// Pseudo-code example
function accessLogs() {
    // Attacker locates sensitive log files within the system
    logs = getSensitiveLogs();
    
    // Attacker retrieves sensitive user information from log files
    sensitiveInfo = extractSensitiveInfo(logs);
    
    // Attacker uses sensitive information to elevate privileges
    elevatePrivileges(sensitiveInfo);
}
