#VU16702 Stack-based buffer overflow in Trusteer Rapport

Vulnerability identifier: #VU16702

Vulnerability risk: Low

CVSSv4.0: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear

CVE-ID: N/A

CWE-ID: CWE-121

Exploitation vector: Local access

Exploit availability: No public exploit available

Vulnerable software:
Trusteer Rapport

Software vendor:
IBM Corporation

The vulnerability allows a local attacker to gain elevated privileges on the target system.

The vulnerability exists due to a signedness bug in validating the user-supplied number of elements provided by the user in the structure passed to the Kernel driver function. A local attacker can perform a call to an struct method exported from the Kernel driver with the IOService 'com_trusteer_rapportke_v2', trigger stack-based buffer overflow and execute arbitrary code in the context of the service daemon.

Successful exploitation of the vulnerability may result in system compromise.

Cybersecurity Help is currently unaware of any official solution to address the vulnerability.
