Detailsinfo

A vulnerability classified as critical has been found in rConfig Core and Pro (affected version not known). Affected is some unknown functionality of the component Queue Handler. The manipulation with an unknown input leads to a deserialization vulnerability. CWE is classifying the issue as CWE-502. The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

rConfig Core 8.0.0 before 8.2.19 and rConfig Pro before 8.4.1 contain a deserialization of untrusted data vulnerability that allows unauthenticated network attackers to execute arbitrary code by pushing a crafted serialized job onto the Redis-backed Laravel Horizon queue, which runs without authentication in affected deployments. Laravel's CallQueuedHandler unserializes the job without class restrictions, allowing attackers to instantiate the existing App\\Jobs\\TaskDownloadRun class and invoke an attacker-controlled Artisan command. Attackers can leverage the bundled laravel/tinker package to execute arbitrary PHP and operating system commands as the queue worker's user, write a persistent web shell into the web-served storage/app/public directory, and read database credentials, stored device credentials, and API tokens. Where Redis is not directly reachable, authenticated attackers can deliver the payload through the application by configuring a device target that points at the rConfig server's loopback address.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-124079 since 11/06/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. The technical details are unknown and an exploit is not available. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 11/09/2026).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
