The shift to cloud means securing your organization's digital assets requires a proactive, multilayered approach.
The group seeks out aerospace professionals by impersonating job recruiters — a demographic it has targeted in the past as well — then deploys the SlugResin backdoor malware.
### Summary A vulnerability exists in the Create User process, allowing the creation of a new admin account with an option to upload a profile image. An attacker can upload a malicious SVG file containing an embedded script. When the profile image is accessed, the embedded script executes, leading to the potential theft of session cookies. ### Details 1. Login as admin 2. Go to Create User 3. Fill up everything in the registration form then upload SVG image as a profile picture 4. In SVG image, add script tag to prepare for XSS attack 5. Complete the Create User process 6. Right click at the image to obtain image URL address 7. XSS triggered ### PoC The below link is a private YouTube video for PoC. https://youtu.be/5j8owD0--1A ### Impact The stored XSS can lead to session hijacking and privilege escalation, effectively bypassing any CSRF protections in place.
### Description Whan consuming a persisted remember-me cookie, symfony does not check if the username persisted in the database matches the username attached with the cookie, leading to authentication bypass. ### Resolution The `PersistentRememberMeHandler` class now ensures the submitted username is the cookie owner. The patch for this issue is available [here](https://github.com/symfony/symfony/commit/81354d392c5f0b7a52bcbd729d6f82501e94135a) for branch 5.4. ### Credits We would like to thank Moritz Rauch - Pentryx AG for reporting the issue and Jérémy Derussé for providing the fix.
### Impact The meeting embeds feature used in the online or hybrid meetings is subject to potential XSS attack through a malformed URL. ### Patches Not available ### Workarounds Disable the creation of meetings by participants in the meeting component. ### References OWASP ASVS v4.0.3-5.1.3 ### Credits This issue was discovered in a security audit organized by mitgestalten Partizipationsbüro against Decidim. The security audit was implemented by the Austrian Institute of Technology.
Ubuntu Security Notice 7100-2 - Supraja Sridhara, Benedict Schlüter, Mark Kuhne, Andrin Bertschi, and Shweta Shinde discovered that the Confidential Computing framework in the Linux kernel for x86 platforms did not properly handle 32-bit emulation on TDX and SEV. An attacker with access to the VMM could use this to cause a denial of service or possibly execute arbitrary code. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

### Summary Missing `normalizePath` in the function `FileHelper::absolutePath` could lead to Remote Code Execution on the server via twig SSTI. `(Post-authentication, ALLOW_ADMIN_CHANGES=true)` ### Details Note: This is a sequel to [CVE-2023-40035](https://github.com/craftcms/cms/security/advisories/GHSA-44wr-rmwq-3phw) In [`src/helpers/FileHelper.php#L106-L137`](https://github.com/craftcms/cms/blob/5e56c6d168524ed02f0620c9bc1c9750f5b94e3b/src/helpers/FileHelper.php#L106-L137), the function `absolutePath` returned `$from . $ds . $to` without path normalization: ```php /** * Returns an absolute path based on a source location or the current working directory. * * @param string $to The target path. * @param string|null $from The source location. Defaults to the current working directory. * @param string $ds the directory separator to be used in the normalized result. Defaults to `DIRECTORY_SEPARATOR`. * @return string * @since 4.3.5 */ public static function absolutePath( ...
### Summary By abusing the mail notification template it is possible to read arbitrary operating system files. ### Details The [dataUrl](https://craftcms.com/docs/3.x/dev/functions.html#dataurl) function can be exploited if an attacker has write permissions on system notification templates. This function accepts an absolute file path, reads the file's content, and converts it into a Base64-encoded string. By embedding this function within a system notification template, the attacker can exfiltrate the Base64-encoded file content through a triggered system email notification. Once the email is received, the Base64 payload can be decoded, allowing the attacker to read arbitrary files on the server. Requirements: * write permissions to system notification templates * ability to trigger a corresponding system email ### PoC 1) Modify a template to contain the following twig template string: ```twig {{ dataUrl('/var/www/web/.env') }} ``` 2) Trigger the corresponding notification email (e...
### Summary A vulnerability in CraftCMS allows an attacker to bypass local file system validation by utilizing a double `file://` scheme (e.g., `file://file:////`). This enables the attacker to specify sensitive folders as the file system, leading to potential file overwriting through malicious uploads, unauthorized access to sensitive files, and, under certain conditions, remote code execution (RCE) via Server-Side Template Injection (SSTI) payloads. Note that this will only work if you have an authenticated administrator account with [allowAdminChanges enabled](https://craftcms.com/docs/5.x/reference/config/general.html#allowadminchanges). https://craftcms.com/knowledge-base/securing-craft#set-allowAdminChanges-to-false-in-production ### Details The issue lies in line 57 of `cms/src/helpers/FileHelper.php`, it only removes `file://` on the most left. It is trivial to bypass this sanitization by adding 2 `file://`, e.g. `file://file:////`. ```php public static function normaliz...
