Description
Description
PostgreSQL Anonymizer contains a vulnerability that allows unprivileged masked users to repeatedly call the anon.hash() function and collects (seed, hash_output) pairs to perform an offline brute-force attack and deduce the salt. A masked role can run a RESTRICTED function when the call is placed inside the sub-select. The problem is resolved in PostgreSQL Anonymizer 3.2.3 and later versions

KEV
| CWE ID | Description |
|---|---|
| CWE-328 | The product uses an algorithm that produces a digest (output value) that does not meet security expectations for a hash function that allows an adversary to reasonably determine the original input (preimage attack), find another input that can produce the same hash (2nd preimage attack), or find multiple inputs that evaluate to the same hash (birthday attack). |
