Insecure Deserialization in SAP NetWeaver Business Client
CVSS Score
7.8
EPSS Score
0.0%
EPSS Percentile
0th
SAP NetWeaver Business Client does not perform sufficient validation when processing certain locally stored data during application startup. An attacker with low privileges on the local system could replace this data with specially crafted content. When the application is next launched, the crafted content is processed and could lead to arbitrary code execution in the context of the user. This results in a high impact on confidentiality, integrity and availability of the application.
