In WinRAR versions prior to and including 5.61, There is path traversal vulnerability when crafting the filename field of the ACE format (in UNACEV2.dll). When the filename field is manipulated with specific patterns, the destination (extraction) folder is ignored, thus treating the filename as an absolute path.

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 Strý?ek from ESET.

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.

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.

RAR Password Recovery 1.80 contains a buffer overflow vulnerability that allows local attackers to crash the application by supplying an oversized payload in the registration dialog. Attackers can craft a malicious input string exceeding 6000 bytes and paste it into the User Name and Registration Code field to trigger an application crash.

RARLAB WinRAR contains a path traversal vulnerability allowing an attacker to execute code in the context of the current user.

Stack-based buffer overflow in Far Manager 1.70beta1 and earlier allows local users to cause a denial of service (crash) and possibly execute arbitrary code via a long pathname.

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 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."

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.

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 WinRAR before 7.00, on Windows, allows attackers to spoof the screen output via ANSI escape sequences, a different issue than CVE-2024-33899.

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.

In WinRAR versions prior to and including 5.61, there is path traversal vulnerability when crafting the filename field of the ACE format. The UNACE module (UNACEV2.dll) creates files and folders as written in the filename field even when WinRAR validator noticed the traversal attempt and requestd to abort the extraction process. the operation is cancelled only after the folders and files were created but prior to them being written, therefore allowing the attacker to create empty files and folders everywhere in the file system.

In WinRAR versions prior to and including 5.60, there is an out-of-bounds write vulnerability during parsing of crafted ACE and RAR archive formats. Successful exploitation could lead to arbitrary code execution in the context of the current user.

UnRAR before 5.5.7 allows remote attackers to bypass a directory-traversal protection mechanism via vectors involving a symlink to the . directory, a symlink to the .. directory, and a regular file.

The Repair Archive command in WinRAR 3.40 allows remote attackers to cause a denial of service (application crash) via a corrupt ZIP archive.

WinRAR 3.40, and possibly earlier versions, allows remote attackers to execute arbitrary code via a ZIP file containing a file with a long filename, possibly causing an integer overflow that leads to a buffer overflow.

Multiple directory traversal vulnerabilities in LHA 1.14 allow remote attackers or local users to create arbitrary files via an LHA archive containing filenames with (1) .. sequences or (2) absolute pathnames with double leading slashes ("//absolute/path").

Multiple stack-based buffer overflows in the getheader function in header.c for LHA 1.14, as used in products such as Barracuda Spam Firewall, allow remote attackers or local users to execute arbitrary code via long directory or file names in an LHA archive, which triggers the overflow when testing or extracting the archive.

Buffer overflow in WinRAR 3.50 and earlier allows local users to execute arbitrary code via a long command-line argument. NOTE: because this program executes with the privileges of the invoking user, and because remote programs do not normally have the ability to specify a command-line argument for this program, there may not be a typical attack vector for the issue that crosses privilege boundaries. Therefore this may not be a vulnerability.

Buffer overflow in the "Add to archive" command in WinRAR 3.51 allows user-assisted attackers to cause a denial of service (crash) and possibly execute arbitrary code by tricking the user into adding a file whose filename contains a non-default code page and non-ANSI characters, as demonstrated using a Chinese filename, possibly due to buffer expansion when using the WideCharToMultiByte API. NOTE: it is not clear whether this problem can be exploited for code execution. If not, then perhaps the user-assisted nature of the attack should exclude the issue from inclusion in CVE.

Stack-based buffer overflow in UNACEV2.DLL for RARLAB WinRAR 2.90 through 3.50 allows remote attackers to execute arbitrary code via an ACE archive containing a file with a long name.

Format string vulnerability in RARLAB WinRAR 2.90 through 3.50 allows remote attackers to execute arbitrary code via format string specifiers in a UUE/XXE file, which are not properly handled when WinRAR displays diagnostic errors related to an invalid filename.

Directory traversal vulnerability in WinRAR 3.42 and earlier, when the user clicks on the ZIP file to extract it, allows remote attackers to create arbitrary files via a ... (triple dot) in the filename of the ZIP file.
