EUVDB-ID: #VU8430

Risk: High

CVSSv4.0: 7.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber]

CVE-ID: CVE-2017-2816

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists in the tag parsing functionality due to out-of-bounds write when handling malicious input. A remote attacker can trick the victim into opening a specially crafted OFX file, trigger stack-based buffer overflow and execute arbitrary code with privileges of the current user.

Successful exploitation of the vulnerability may result in system compromise.

Mitigation

Cybersecurity Help is currently unaware of any official patch addressing the vulnerability.
