تسمح هذه الثغرة بتسجيل ملفات عشوائية باسم مستخدم OSV-SCALIBR على النظام المضيف من خلال ثغرة في اجتياز المسار (path traversal) عند استخدام دالة unpack() في OSV-SCALIBR لصور الحاويات. ويشكل هذا مشكلة كبيرة بشكل خاص عند استخدام علامة CLI --remote-image مع صور الحاويات غير الموثوق بها.

The Linux kernel is susceptible to a vulnerability stemming from an incorrect verifier pruning in BPF. This flaw allows unsafe code paths to be incorrectly marked as safe, potentially leading to arbitrary read/write access in kernel memory, lateral privilege escalation, and container escape. The vulnerability affects Linux Kernel versions 5.4 and later. The `backtrack insn()` function within the kernel/bpf/verifier.c module is implicated in this issue.

The vulnerability is due to enabling XML entity substitution that may result in XML external entity injection. An attacker could exploit this vulnerability by submitting a crafted DMG file to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to leak bytes from any file that may be read by the ClamAV scanning process.

The issue is related to a missing buffer size check in the HFS+ partition file parser of ClamAV, which may result in a heap buffer overflow write. An attacker could exploit this by submitting a crafted HFS+ partition file to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to execute arbitrary code with the privileges of the ClamAV scanning process or crash the process, resulting in a denial of service condition.

The issue allows a remote unauthenticated attacker to obtain the email address of the user who posted a blog using the WordPress Post by Email Feature.

The issue allows for XSS via a crafted email message in the Email Viewer. This can potentially be exploited to steal users' emails.

The issue allows an unauthenticated attacker to inject arbitrary memcache commands into a targeted instance, causing an overwrite of arbitrary cached entries. This can be exploited to execute arbitrary commands and potentially steal user credentials. The vulnerability is being actively exploited.

The issue concerns a free and open-source content management system written in PHP and paired with a MariaDB database. On a multisite, users with Super Admin role can bypass explicit/additional hardening under certain conditions through object injection.

Low-privileged authenticated users, such as authors, in the WordPress core are able to execute JavaScript and perform a stored XSS attack, which can affect high-privileged users.

The issue allows an out-of-bounds read in the core interpreter, leading to code execution. If a victim executes an attacker-controlled Squirrel script, it is possible for the attacker to break out of the Squirrel script sandbox, even if all dangerous functionality, such as File System functions, has been disabled. An attacker might abuse this bug to target Cloud services that allow customization via Squirrel scripts or distribute malware through video games that embed a Squirrel Engine.

The issue allows stored XSS, with resultant code execution, because an uploaded file can be placed in an IFRAME element within user-generated content. For code execution, the attacker can rely on the ability of an admin to install widgets, disclosure of the admin session ID in a Referer header, and the ability of an admin to use the templating engine (e.g., Edit HTML).

The issue allows reflected XSS because the filenames of uploaded files become predictable through a brute-force attack against the PHP mt rand function. This predictability can be exploited to conduct reflected XSS attacks.

Name of the Vulnerable Software and Affected Versions: Zimbra Collaboration Suite versions 8.8.0 through 8.8.15 Patch 22 Zimbra Collaboration Suite versions 9.0.0 through 9.0.0 Patch 15 Description: An issue was discovered in ProxyServlet.java in the /proxy servlet. The value of the `X-Host` header overwrites the value of the `Host` header in proxied requests. The value of `X-Host` header is not checked against the whitelist of hosts Zimbra is allowed to proxy to, which is defined by the `zimbraProxyAllowedDomains` setting. Recommendations: For Zimbra Collaboration Suite versions 8.8.0 through 8.8.15 Patch 22, update to version 8.8.15 Patch 23 or later. For Zimbra Collaboration Suite versions 9.0.0 through 9.0.0 Patch 15, update to version 9.0.0 Patch 16 or later. As a temporary workaround, consider restricting the `X-Host` header to only allow trusted hosts until a patch is applied.

Name of the Vulnerable Software and Affected Versions: Zimbra Collaboration Suite versions 8.8.x through 8.8.15 Patch 22 Description: An issue was discovered in the Calendar Invite component, specifically in ZmMailMsgView.js. This issue allows an attacker to place HTML containing executable JavaScript inside element attributes, which becomes unescaped and causes arbitrary markup to be injected into the document. Recommendations: For Zimbra Collaboration Suite versions 8.8.x through 8.8.15 Patch 22, update to version 8.8.15 Patch 23 or later to resolve the issue. As a temporary workaround, consider restricting the use of the Calendar Invite component until a patch is applied.

Name of the Vulnerable Software and Affected Versions: Zimbra Collaboration Suite versions prior to 9.0 Description: An open redirect issue exists in the /preauth Servlet. To exploit this, an attacker needs a valid zimbra auth token or preauth token. With the token, an attacker can redirect a user to any URL using the "isredirect=1&redirectURL=" parameter in conjunction with the token data, such as a valid "authtoken=" value. Recommendations: For Zimbra Collaboration Suite versions prior to 9.0, update to version 9.0 or later to resolve the issue. As a temporary workaround, consider restricting access to the /preauth Servlet to minimize the risk of exploitation. Avoid using the "isredirect=1&redirectURL=" parameter in the affected API endpoint until the issue is resolved.

The issue is related to a Cross-Site Scripting (XSS) error in the block editor of the WordPress content management system. This error can be exploited by authenticated users with lower privileges, such as contributors, who can inject JavaScript code in the block editor. The injected code is executed within the dashboard, which can lead to an admin opening the affected post in the editor, resulting in an XSS attack. This can allow a remote attacker to compromise the integrity of the data.

The issue is related to a parsing flaw in the Private Message / Post renderer, specifically a nested video MyCode issue, which can lead to persistent XSS. This allows an attacker to potentially take over any forum account.

The issue allows an attacker to create a PHP shell in the cache directory of a targeted forum via a crafted XML import. This is achieved by exploiting a default behavior of MySQL on many systems, where strings that are too long for a database column are truncated. For example, a string like `aaaaaaaaaaaaaaaaaaaaaa.php.css` can be truncated to `aaaaaaaaaaaaaaaaaaaaaa.php` due to a 30-character limit, leading to remote code execution.

The issue is related to a double free error in the `gdImage*Ptr()` functions within the files `gd gif out.c`, `gd jpeg.c`, and `gd wbmp.c` of the graphic library. This could allow a remote attacker to impact the confidentiality, integrity, and availability of protected information.

The issue allows for Remote Code Execution through Object Injection by utilizing Phar deserialization. This can be achieved by passing an absolute path to a file exists check. The exploitation of this issue requires access to the Admin Control Panel with founder permissions.
