EXPLOIT

Real Networks Netzip Classic version 7.5.1.86 is vulnerable to a stack-based buffer overflow when parsing a specially crafted ZIP archive. The vulnerability is triggered when the application attempts to process a file name within the archive that exceeds the expected buffer size. Exploitation allows arbitrary code execution under the context of the victim user when the ZIP file is opened.

Detection & IOCs extracted from sources · hover to see the quote

• → Vulnerability is triggered by a ZIP archive containing a filename that exceeds the expected buffer size; monitor for ZIP files with abnormally long filenames being opened by NetZip Classic. ↗
• → Exploitation requires user interaction — an attacker must deliver a specially crafted ZIP file and convince the victim to open it with NetZip Classic; monitor for suspicious ZIP file delivery via email or web to users running NetZip Classic 7.5.1.86. ↗

• · Affected version is specifically Real Networks Netzip Classic 7.5.1.86 (Windows); exploitation results in code execution under the victim user's context only — no privilege escalation beyond the current user. ↗
• · The Metasploit module targets the fileformat vector (file-based exploitation), meaning no network listener is required on the victim side; the attack is entirely client-side. ↗
