Vulnerability description

The specialists of the Positive Research center have detected "Information disclosure" vulnerability in SAP.

An Information Leakage vulnerability exists in the way SAProuter works with dynamic memory.
The cause of the leakage is that SAProuter does not clear the dynamically captured memory before reusing it.
The vulnerability may (on certain conditions) allow attackers to obtain configuration files contents (including routing rules and access passwords).

Moreover, the vulnerability potentially allows an attacker to obtain other users’ traffic that passes through SAProuter.

Routing table can be obtained by attackers after administrator locally executes the saprouter –n command (which activates configuration file changes).
