Very high risk99th percentile - higher than 99% of all known CVEs
Summary
In Redis 7.0 prior to 7.0.12, a vulnerability exists that may lead to a heap overflow when extracting key names from a command and a list of arguments. This can result in reading random heap memory, heap corruption, and potentially remote code execution.
Risk Assessment
Organizations may be exposed to attacks that allow authenticated users to execute malicious commands, potentially leading to serious security breaches.
Recommendation
It is recommended to upgrade Redis to version 7.0.12 or later to mitigate this vulnerability.
Original NVD description (English source)
Redis is an in-memory database that persists on disk. In Redit 7.0 prior to 7.0.12, extracting key names from a command and a list of arguments may, in some cases, trigger a heap overflow and result in reading random heap memory, heap corruption and potentially remote code execution. Several scenarios that may lead to authenticated users executing a specially crafted `COMMAND GETKEYS` or `COMMAND GETKEYSANDFLAGS`and authenticated users who were set with ACL rules that match key names, executing a specially crafted command that refers to a variadic list of key names. The vulnerability is patched in Redis 7.0.12.
