RabbitMQ URI Deobfuscation in Shovel/Federation Plugins before 3.10.2
CVE-2022-31008 Published on October 6, 2022
Predictable credential obfuscation seed value used in rabbitmq-server
RabbitMQ is a multi-protocol messaging and streaming broker. In affected versions the shovel and federation plugins perform URI obfuscation in their worker (link) state. The encryption key used to encrypt the URI was seeded with a predictable secret. This means that in case of certain exceptions related to Shovel and Federation plugins, reasonably easily deobfuscatable data could appear in the node log. Patched versions correctly use a cluster-wide secret for that purpose. This issue has been addressed and Patched versions: `3.10.2`, `3.9.18`, `3.8.32` are available. Users unable to upgrade should disable the Shovel and Federation plugins.
Vulnerability Analysis
CVE-2022-31008 is exploitable with local system access, and requires small amount of user privileges. This vulnerability is considered to have a low attack complexity. The potential impact of an exploit of this vulnerability is considered to have a high impact on confidentiality, with no impact on integrity and availability.
Weakness Type
Use of Insufficiently Random Values
The software uses insufficiently random numbers or values in a security context that depends on unpredictable numbers. When software generates predictable values in a context requiring unpredictability, it may be possible for an attacker to guess the next value that will be generated, and use this guess to impersonate another user or access sensitive information.
