CVE-2026-62648: CWE-787: Out-of-bounds Write in Siemens Reyrolle 7SR5
A vulnerability has been identified in Reyrolle 7SR5 (All versions < V2.70). The length of the URL component contained in pre-authenticated HTTP messages is not properly validated before appending additional data to it, resulting in an out-of-bounds write condition in memory. This could allow an unauthenticated remote attacker to crash the affected device, causing a reboot and resulting in a denial-of-service condition.
AI Analysis
Technical Summary
CVE-2026-62648 is an out-of-bounds write vulnerability (CWE-787) affecting Siemens Reyrolle 7SR5 devices with firmware versions earlier than 2.70. The vulnerability occurs because the length of the URL component in pre-authenticated HTTP requests is not properly validated before additional data is appended, leading to memory corruption. Exploitation requires no authentication and can cause the device to crash and reboot, causing a denial-of-service condition. There is no vendor advisory or patch information currently available, and no known exploits in the wild have been reported.
Potential Impact
An unauthenticated remote attacker can exploit this vulnerability to cause an out-of-bounds write in memory, leading to a device crash and reboot. This results in a denial-of-service condition, potentially disrupting the availability of the affected Siemens Reyrolle 7SR5 device. There is no indication of confidentiality or integrity impact.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, limit exposure of the affected device to untrusted networks and monitor for unusual device reboots or crashes.
