SAP Patches Critical Extended Passport Processing Vulnerability

01What broke

SecurityWeek reports: SAP Patches Critical Extended Passport Processing Vulnerability. Affecting the SAP kernel code, the flaw allows unauthenticated, remote attackers to run arbitrary commands, recover secrets, and modify data. The post SAP Patches Critical Extended Passport Processing Vulnerability appeared first on SecurityWeek .

SAP released 20 new and updated security notes on Tuesday, including one that resolves a critical-severity memory corruption vulnerability. Tracked as CVE-2026-44756 (CVSS score of 10/10), the critical bug is described as a memory corruption issue in Extended Passport (EPP) Processing.

02Who is exposed

Missing boundary validations during the deserialization of EPP data could trigger unsafe memory behavior during the processing of externally supplied length fields, application security firm Onapsis explains. Dubbed OVERPASS, the security defect can be exploited by unauthenticated attackers to run arbitrary system commands, recover database credentials and password hashes, read the live sessions of logged-in users, and modify data, including configurations and SAP binaries.

03What to do now

According to Onapsis, the flaw resides in the SAP kernel code and impacts various components, as EPP is used for tracing within multiple SAP applications. See the full write-up from SecurityWeek via the source link for quotes and complete context.

“Because EPP is processed as the session opens, every SAP control that decides who may do what, including user locks, roles, authorization objects, and logon policies, is evaluated later than the point where the flaw is reached. Additionally, it says, the bug can be reached via at least three vectors, including web requests, the SAP GUI protocol, and Remote Function Call (RFC) connections.

04How the issue works

“The affected components run under the operating system account that owns the SAP installation, so code execution under it is equivalent to owning the SAP system outright,” Onapsis says. SAP products that rely on the vulnerable kernel code include S/4HANA, ERP, Business Suite (ECC), NetWeaver, Web Dispatcher, BW/4HANA, Enterprise Portal, PI/PO, Solution Manager, and others.

05What is still unknown

According to Onapsis, there are no indicators that the vulnerability has been exploited in the wild. See the full write-up from SecurityWeek via the source link for quotes and complete context.
