A use of externally-controlled format string vulnerability has been reported to affect several QNAP operating system versions. If a remote attacker gains an administrator account, they can then exploit the vulnerability to obtain secret data or modify memory. We have already fixed the vulnerability in the following versions: QTS 5.2.7.3256 build 20250913 and later QuTS hero h5.2.7.3256 build 20250913 and later QuTS hero h5.3.1.3250 build 20250912 and laterShow less

WM Downloader version 3.1.2.2 is vulnerable to a buffer overflow when processing a specially crafted .m3u playlist file. The application fails to properly validate input length, allowing an attacker to overwrite structured exception handler (SEH) records and execute arbitrary code.

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to ImageMagick versions 6.9.13-28 and 7.1.2-2, a format string bug vulnerability exists in InterpretImageFilename function where user input is directly passed to FormatLocaleString without proper sanitization. An attacker can overwrite arbitrary memory regions, enabling a wide range of attacks from heap overflow to remote code execution. This issue has been patched in versions 6.9.13-28 and 7.1.2-2.Show less

ComSndFTP FTP Server version 1.3.7 Beta contains a format string vulnerability in its handling of the USER command. By sending a specially crafted username containing format specifiers, a remote attacker can overwrite a hardcoded function pointer in memory (specifically WSACleanup from Ws2_32.dll). This allows the attacker to redirect execution flow and bypass DEP protections using a ROP chain, ultimately leading to arbitrary code execution. The vulnerability is exploitable without authentication and affects default configurations.Show less

An issue was discovered in CommScope Ruckus Unleashed prior to 200.15.6.212.14 and 200.17.7.0.139, where the functions `stamgr_cfg_adpt_addStaFavourite` and `stamgr_cfg_adpt_addStaIot` pass a client hostname directly to snprintf as the format string. A remote attacker can exploit this flaw either by sending a crafted request to the authenticated endpoint `/admin/_conf.jsp`, or without authentication and without direct network access to the controller by spoofing the MAC address of a favourite station and embedding malicious format specifiers in the DHCP hostname field, resulting in unauthenticated format-string processing and arbitrary code execution on the controller.Show less

FreeScout is a free self-hosted help desk and shared mailbox. Prior to version 1.8.178, the application performs insufficient validation of user-supplied data, which is used as arguments to string formatting functions. As a result, an attacker can pass a string containing special symbols (\r, \n, \t)to the application. This issue has been patched in version 1.8.178.Show less
