Vulnerabilities in this advisory
- CVE-2026-27663 — CVE-2026-27663 · CWE-770
The affected application contains denial-of-service (DoS) vulnerability. The remote operation mode is susceptible to a resource exhaustion condition when subjected to a high volume of requests. Sending multiple requests can exhaust resources, preventing parameterization and requiring a reset or reboot to restore functionality.
- CVE-2026-27664 — CVE-2026-27664 · CWE-787
The affected application contains an out-of-bounds write vulnerability while parsing specially crafted XML inputs. This could allow an unauthenticated attacker to exploit this issue by sending a malicious XML request, which may cause the service to crash, resulting in a denial-of-service condition.
