Telesquare TLR-2005KSH 1.1.4 is affected by an unauthorized command execution vulnerability when requesting the admin.cgi parameter with setAutorest.

Executive ViewAI

Why It Matters

Organizations using Telesquare TLR-2005KSH 1.1.4 face critical risk from CVE-2025-26003, a code injection vulnerability rated CVSS 9.8. Successful exploitation could allow attackers to execute arbitrary code or commands on affected systems, potentially leading to full system compromise. Organizations should apply vendor updates immediately when available and implement compensating controls in the interim.

Business Impact: Severe

Compensating Controls

Apply vendor patch. If immediate patching is not feasible: (1) Deploy WAF rules to block injection patterns; (2) Restrict network access to affected components; (3) Enable enhanced logging for suspicious activity.

Attack Technique

Code Injection CRITICAL

Code injection occurs when an application accepts user input and passes it directly into a language interpreter or evaluator without proper sanitization.

Remote Code Execution CRITICAL

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
