Detection & IOCsextracted from sources · hover to see the quote
- →Detect unauthenticated or low-privilege POST requests to the webuser update endpoint (?c=webuser&m=update) with UserRole=1 in the POST body, indicating privilege escalation attempts on Linear eMerge E3-Series devices. ↗
- →Detect GET requests to the webuser select endpoint (?c=webuser&m=select) which can be used for unauthorized information disclosure of user credentials on Linear eMerge E3-Series devices. ↗
- →Monitor for authorization bypass patterns where the ?c=webuser controller endpoint is accessed without proper privilege validation, covering both m=update (escalation) and m=select (disclosure) actions. ↗
- ·The exploit PoC uses a hardcoded private IP (192.168.1.2); in real deployments the target IP will vary. Detection rules should match on the URI path patterns (?c=webuser&m=update and ?c=webuser&m=select) rather than the destination IP. ↗
- ·The exploit was tested against firmware version 1.00-06 of the Linear eMerge E3-Series. Other firmware versions may present the same vulnerable endpoints but have not been explicitly confirmed in this PoC. ↗
