Vulnerability from fkie_nvd - Published: 2026-07-14 01:16 - Updated: 2026-07-14 16:46

Severity

7.6 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:L

Summary

SAP Change and Transport System Attach Tool (ctsattach) allows an authenticated attacker to supply a specially crafted archive file which, when processed by the application�s library, can trigger insecure deserialization and lead to remote code execution (RCE) on the system. Successful exploitation requires a victim to process the malicious archive, enabling the attacker to execute the RCE and extract sensitive information and gain control over the system and its processes. This vulnerability has a high impact on confidentiality and integrity of the data, with a low impact on the availability of the system.
