CVE-2017-7722

Status: ModifiedCritical (10)—💥 Exploit

In SolarWinds Log & Event Manager (LEM) before 6.3.1 Hotfix 4, a menu system is encountered when the SSH service is accessed with "cmc" and "password" (the default username and password). By exploiting a vulnerability in the restrictssh feature of the menuing script, an attacker can escape from the restricted shell.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
