WinRAR 5.61 contains a denial of service vulnerability that allows local attackers to crash the application by placing a malformed winrar.lng language file in the installation directory. Attackers can trigger the crash by opening an archive and pressing the test button, causing an access violation at memory address 004F1DB8 when the application attempts to read invalid data.
A security vulnerability has been detected in Rarlab RAR App up to 7.11 Build 127 on Android. This affects an unknown part of the component com.rarlab.rar. Such manipulation leads to path traversal. It is possible to launch the attack remotely. Attacks of this nature are highly complex. It is indicated that the exploitability is difficult. The exploit has been disclosed publicly and may be used. Upgrading to version 7.20 build 128 is able to mitigate this issue. You should upgrade the affected component. The vendor responded very professional: "This is the real vulnerability affecting RAR for Android only. WinRAR and Unix RAR versions are not affected. We already fixed it in RAR for Android 7.20 build 128 and we publicly mentioned it in that version changelog. (...) To avoid confusion among users, it would be useful if such disclosure emphasizes that it is RAR for Android only issue and WinRAR isn't affected."
Cross-site scripting (XSS) vulnerability in the generate report functionality in Rarlab WinRAR 7.11, allows attackers to disclose user information such as the computer username, generated report directory, and IP address. The generate report command includes archived file names without validation in the HTML report, which allows potentially malicious HTML tags to be injected into the report. User interaction is required. User must use the "generate report" functionality and open the report.
A path traversal vulnerability affecting the Windows version of WinRAR allows the attackers to execute arbitrary code by crafting malicious archive files. This vulnerability was exploited in the wild and was discovered by Anton Cherepanov, Peter Košinár, and Peter Strýček
from ESET.
RARLAB WinRAR Directory Traversal Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of RARLAB WinRAR. 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 file paths within archive files. A crafted file path can cause the process to traverse to unintended directories. An attacker can leverage this vulnerability to execute code in the context of the current user. Was ZDI-CAN-27198.
Issue that bypasses the "Mark of the Web" security warning function for files when opening a symbolic link that points to an executable file exists in WinRAR versions prior to 7.11. If a symbolic link specially crafted by an attacker is opened on the affected product, arbitrary code may be executed.
RARLAB WinRAR Recovery Volume Improper Validation of Array Index Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of RARLAB WinRAR. 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 processing of recovery volumes. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-21233.
RARLAB WinRAR before 7.00, on Linux and UNIX platforms, allows attackers to spoof the screen output, or cause a denial of service, via ANSI escape sequences.
RARLAB WinRAR Mark-Of-The-Web Bypass Vulnerability. This vulnerability allows remote attackers to bypass the Mark-Of-The-Web protection mechanism on affected installations of RARLAB WinRAR. User interaction is required to exploit this vulnerability in that the target must perform a specific action on a malicious page.
The specific flaw exists within the archive extraction functionality. A crafted archive entry can cause the creation of an arbitrary file without the Mark-Of-The-Web. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current user. Was ZDI-CAN-23156.
RARLAB WinRAR before 6.23 allows attackers to execute arbitrary code when a user attempts to view a benign file within a ZIP archive. The issue occurs because a ZIP archive may include a benign file (such as an ordinary .JPG file) and also a folder that has the same name as the benign file, and the contents of the folder (which may include executable content) are processed during an attempt to access only the benign file. This was exploited in the wild in April through October 2023.
This vulnerability allows remote attackers to disclose sensitive information on affected installations of RARLAB WinRAR 6.11.0.0. 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 parsing of ZIP files. Crafted data in a ZIP file can trigger a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process. Was ZDI-CAN-19232.
RARLAB UnRAR before 6.12 on Linux and UNIX allows directory traversal to write to files during an extract (aka unpack) operation, as demonstrated by creating a ~/.ssh/authorized_keys file. NOTE: WinRAR and Android RAR are unaffected.
