- CWE-787 - Out-of-bounds Write
Summary
A vulnerability has been identified in CPCI85 Central Processing/Communication (All versions < V26.10), SICORE Base system (All versions < V26.10.0). 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.
