CWE ID Description
CWE-121 A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
CWE-119 The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.

Executive Summary

CVE-2026-19341 is a stack-based buffer overflow vulnerability in the UTT HiPER 1200GW router firmware up to version 2.5.3-170306. It occurs in the /goform/pptpSrvGlobalConfig endpoint where the strcpy function improperly handles the EncryptionMode parameter, allowing attackers to overflow the stack. This can lead to denial of service or remote code execution.

Detection Guidance

To detect this vulnerability, monitor network traffic for HTTP POST requests targeting the /goform/pptpSrvGlobalConfig endpoint with malformed EncryptionMode parameters. Check router logs for unusual activity or crashes. Use network scanners to identify UTT HiPER 1200GW devices running firmware versions up to v2.5.3-170306.

Impact Analysis

This vulnerability allows remote attackers to execute arbitrary code or cause a denial of service on affected UTT HiPER 1200GW routers. An attacker could send a crafted HTTP POST request to the vulnerable endpoint, potentially gaining control of the device or disrupting its operation.

Compliance Impact

This vulnerability does not directly affect compliance with GDPR or HIPAA as it is a technical flaw in a network device. However, if exploited, it could lead to unauthorized access or data breaches, which may violate GDPR's data protection requirements or HIPAA's security rules depending on the environment.

Mitigation Strategies

Immediately update the router firmware to the latest version if available. If no patch exists, restrict access to the /goform/pptpSrvGlobalConfig endpoint via firewall rules. Disable PPTP server functionality if not required. Monitor for exploitation attempts and isolate affected devices.
