# Security digest: October 3, 2024

1 known exploited (cisa kev) addition and 1 critical advisory.

## Take stock

- Do you run any of these? Synacor Zimbra Collaboration Suite (ZCS). They are being exploited in the wild (CISA KEV). Patch or mitigate if you do; CISA’s federal deadline is 2024-10-24.
- Maven: 1 critical advisory ( org.apache.avro:avro ). Check with mvn dependency:tree -Dincludes=<groupId>:<artifactId> .
- None of it touches your stack? Then there is nothing to do today. That is a result, not a failure to read carefully.

## Known exploited (CISA KEV)

- [CVE-2024-45519](https://erroneo.us/security/cve/CVE-2024-45519/index.md) Synacor Zimbra Collaboration Suite (ZCS): Synacor Zimbra Collaboration Suite (ZCS) Command Execution Vulnerability (CISA due 2024-10-24)

## Critical advisories
