SAP Web Dispatcher, Internet Communication Manager (ICM), and SAP Content Server allow an unauthenticated user to exploit logical errors that lead to a memory corruption vulnerability. This results in high impact on the availability with no impact on confidentiality or integrity of the application.

CVE-2025-42877 is an out-of-bounds write vulnerability classified under CWE-787, affecting SAP SE's Web Dispatcher, Internet Communication Manager (ICM), and SAP Content Server components. The vulnerability stems from logical errors in the handling of certain requests that cause memory corruption. This memory corruption can be exploited by an unauthenticated attacker remotely, without any user interaction, to cause a denial of service (DoS) by crashing or destabilizing the affected SAP services. The affected versions include multiple SAP kernel and application service versions, notably KRNL64UC 7.53, WEBDISP 7.53, 7.54, XS_ADVANCED_RUNTIME 1.00, SAP_EXTENDED_APP_SERVICES 1, CONTSERV 7.53, and KERNEL 7.53. The vulnerability has a CVSS v3.1 base score of 7.5, indicating high severity, with attack vector network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and impact limited to availability (A:H) without affecting confidentiality or integrity. No patches were linked at the time of reporting, and no known exploits have been observed in the wild. The vulnerability could be leveraged to disrupt SAP services critical for enterprise operations, potentially causing downtime and operational losses. SAP Web Dispatcher and ICM are often deployed as front-end components managing communication and load balancing, while SAP Content Server handles document storage, making their availability crucial for business continuity.
