Bandisoft Bandizip before 7.47 Mark-of-the-Web Bypass for PowerShell Scripts

Bandisoft Bandizip before 7.47 fails to propagate Mark-of-the-Web to extracted .ps1 and .psm1 files, allowing attackers to bypass zone-based execution protections. Attackers can deliver unsigned PowerShell scripts or modules in downloaded archives that run under the RemoteSigned policy when the user invokes them.

Bypass of Mark‑of‑the‑Web Protection in BandiZip 7.37

BandiZip v.7.37 is affected by a Authentication Bypass Vulnerability. This vulnerability allows remote attackers to bypass the Mark-of-the-Web protection mechanism on affected installations of BandiZip

In Bandisoft Bandizip through 7.37, there is a Mark-of-the-Web Bypass Vulnerability. This vulnerability allows attackers to bypass the Mark-of-the-Web protection mechanism on affected installations of Bandizip. 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, Bandizip 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. NOTE: this is disputed because Mark-of-the-Web propagation can increase risk via security-warning habituation, and because the intended control sphere for file-origin metadata (e.g., HostUrl in Zone.Identifier) may be narrower than that for reading the file's content.

Untrusted search path vulnerability in Bandisoft Bandizip before 3.10 allows local users to gain privileges via a Trojan horse dwmapi.dll file in the current working directory.

Bandisoft ARK Library Out-of-bound Vulnerability

A remote code execution vulnerability due to incomplete check for 'xheader_decode_path_record' function's parameter length value in the ark library. Remote attackers can induce exploit malicious code using this function.
