Server-Side Template Injection (SSTI) with Grav CMS security sandbox bypass

Grav is an open-source, flat-file content management system. Grav CMS prior to version 1.7.45 is vulnerable to a Server-Side Template Injection (SSTI), which allows any authenticated user (editor permissions are sufficient) to execute arbitrary code on the remote server bypassing the existing security sandbox. Version 1.7.45 contains a patch for this issue.

A CWE-94: Improper Control of Generation of Code ('Code Injection') vulnerability exists that could cause execution of malicious code when an unsuspicious user loads a project file from the local filesystem into the HMI.

Grav Server Side Template Injection vulnerability

Grav is a flat-file content management system. Versions prior to 1.7.42 are vulnerable to server side template injection. Remote code execution is possible by embedding malicious PHP code on the administrator screen by a user with page editing privileges. Version 1.7.42 contains a fix for this issue.

Remote Code Execution

Zohocorp ManageEngine OpManager and Remote Monitoring and Management versions 128329 and below are vulnerable to the authenticated remote code execution in the deploy agent option.

ruifang-tech Rebuild Task Comment Attachment Upload cross site scripting

A vulnerability, which was classified as problematic, was found in ruifang-tech Rebuild 3.8.5. Affected is an unknown function of the component Task Comment Attachment Upload. The manipulation leads to cross site scripting. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

ruifang-tech Rebuild Project Task Comment cross site scripting

A vulnerability, which was classified as problematic, has been found in ruifang-tech Rebuild 3.8.5. This issue affects some unknown processing of the component Project Task Comment Handler. The manipulation leads to cross site scripting. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Grav vulnerable to Server-side Template Injection (SSTI) via Denylist Bypass

Grav is a flat-file content management system. Prior to version 1.7.42, the denylist introduced in commit 9d6a2d to prevent dangerous functions from being executed via injection of malicious templates was insufficient and could be easily subverted in multiple ways -- (1) using unsafe functions that are not banned, (2) using capitalised callable names, and (3) using fully-qualified names for referencing callables. Consequently, a low privileged attacker with login access to Grav Admin panel and page creation/update permissions is able to inject malicious templates to obtain remote code execution. A patch in version 1.7.42 improves the denylist.

Grav Server-side Template Injection (SSTI) via Twig Default Filters

Grav is a flat-file content management system. Prior to version 1.7.42, the patch for CVE-2022-2073, a server-side template injection vulnerability in Grav leveraging the default `filter()` function, did not block other built-in functions exposed by Twig's Core Extension that could be used to invoke arbitrary unsafe functions, thereby allowing for remote code execution. A patch in version 1.74.2 overrides the built-in Twig `map()` and `reduce()` filter functions in `system/src/Grav/Common/Twig/Extension/GravExtension.php` to validate the argument passed to the filter in `$arrow`.

Grav Server-side Template Injection via Insufficient Validation in filterFilter

Grav is a flat-file content management system. Prior to version 1.7.42, there is a logic flaw in the `GravExtension.filterFilter()` function whereby validation against a denylist of unsafe functions is only performed when the argument passed to filter is a string. However, passing an array as a callable argument allows the validation check to be skipped. Consequently, a low privileged attacker with login access to Grav Admin panel and page creation/update permissions is able to inject malicious templates to obtain remote code execution. The vulnerability can be found in the `GravExtension.filterFilter()` function declared in `/system/src/Grav/Common/Twig/Extension/GravExtension.php`. Version 1.7.42 contains a patch for this issue. End users should also ensure that `twig.undefined_functions` and `twig.undefined_filters` properties in `/path/to/webroot/system/config/system.yaml` configuration file are set to `false` to disallow Twig from treating undefined filters/functions as PHP functions and executing them.

Insecure Permissions vulnerability in Open Robotics Robotic Operating System 2 (ROS2) navigation2- ROS2-humble and navigation 2-humble allows a local attacker to execute arbitrary code via the error-thrown mechanism in nav2_bt_navigator.

In DevmemIntChangeSparse2 of devicemem_server.c, there is a possible way to achieve arbitrary code execution due to a missing permission check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

Multiple Sitecore products allow remote code execution. This affects Experience Manager, Experience Platform, and Experience Commerce through 10.3.

An issue was discovered in SugarCRM Enterprise before 11.0.6 and 12.x before 12.0.3. A Bean Manipulation vulnerability has been identified in the REST API. By using a crafted request, custom PHP code can be injected through the REST API because of missing input validation. Regular user privileges can be used to exploit this vulnerability. Editions other than Enterprise are also affected.

A vulnerability has been identified in SIMATIC CP 343-1 (6GK7343-1EX30-0XE0) (All versions), SIMATIC CP 343-1 Lean (6GK7343-1CX10-0XE0) (All versions), SIPLUS NET CP 343-1 (6AG1343-1EX30-7XE0) (All versions), SIPLUS NET CP 343-1 Lean (6AG1343-1CX10-2XE0) (All versions). Affected products incorrectly validate TCP sequence numbers. This could allow an unauthenticated remote attacker to create a denial of service condition by injecting spoofed TCP RST packets.

Laravel Pulse Allows Remote Code Execution via Unprotected Query Method

Laravel Pulse is a real-time application performance monitoring tool and dashboard for Laravel applications. A vulnerability has been discovered in Laravel Pulse prior to version 1.3.1 that could allow remote code execution through the public `remember()` method in the `Laravel\Pulse\Livewire\Concerns\RemembersQueries` trait. This method is accessible via Livewire components and can be exploited to call arbitrary callables within the application. An authenticated user with access to Laravel Pulse dashboard can execute arbitrary code by calling any function or static method in which the callable is a function or static method and the callable has no parameters or no strict parameter types. The vulnerable to component is `remember(callable $query, string $key = '')` method in `Laravel\Pulse\Livewire\Concerns\RemembersQueries`, and the vulnerability affects all Pulse card components that use this trait. Version 1.3.1 contains a patch.
