cassandra-rs non-idiomatic use of iterators leads to use after free

Collected exploitation and prediction evidence

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

cve-program · CVE-2024-27284

Published

cassandra-rs is a Cassandra (CQL) driver for Rust. Code that attempts to use an item (e.g., a row) returned by an iterator after the iterator has advanced to the next item will be accessing freed memory and experience undefined behaviour. The problem has been fixed in version 3.0.0.

### Impact Code that attempts to use an item (e.g., a row) returned by an iterator after the iterator has advanced to the next item will be accessing freed memory and experience undefined behaviour. Code that uses the item and then advances the iterator is unaffected. This problem has always existed. This is a use-after-free bug, so it's rated high severity. If your code uses a pre-3.0.0 version of cassandra-rs, and uses an item returned by a cassandra-rs iterator after calling `next()` on that iterator, then it is vulnerable. However, such code will almost always fail immediately - so we believe it is unlikely that any code using this pattern would have reached production. For peace of mind, we recommend you upgrade anyway. ### Patches The problem has been fixed in version 3.0.0. Users should upgrade to ensure their code cannot use the problematic pattern. ### Workarounds Ensure all usage fits the expected pattern. For example, use `get_first_row()` rather than an iterator, or completely process an item before advancing the iterator with `next()`. ### References None.
