7-Zip Mark-of-the-Web Bypass Vulnerability. This vulnerability allows remote attackers to bypass the Mark-of-the-Web protection mechanism on affected installations of 7-Zip. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the handling of archived files. When extracting files from a crafted archive that bears the Mark-of-the-Web, 7-Zip does not propagate the Mark-of-the-Web to the extracted files. An attacker can leverage this vulnerability to execute arbitrary code in the context of the current user. Was ZDI-CAN-25456.
CISA has urgently warned federal agencies about the active exploitation of a serious Microsoft Outlook vulnerability, CVE-2024-21413. A remote code execution (RCE) flaw, found by Check Point researcher Haifei Li, is due to improper input validation when handling emails with malicious links.
“Successful exploitation of this vulnerability would allow an attacker to bypass the Office Protected View and open in editing mode rather than protected mode,” Microsoft stated.
The flaw, dubbed the “MonikerLink” bug, enables attackers to exploit hyperlinks using the file:// protocol and manipulate URLs with an exclamation mark followed by arbitrary text.
