Apache Thrift Go bindings: Denial of service via highly compressed data
Summary
The Go bindings of Apache Thrift do not limit the inflated size of ZLIB-compressed frames processed by THeaderTransport. A remote attacker can send specially crafted, highly compressed data to an affected service, causing resource exhaustion and denial of service. Exploitation depends on the deployment, and the issue does not allow code execution or data disclosure.
Affected
- Apache Thrift Go bindings (github.com/apache/thrift) before 0.25.0
- Versions 0.24.0 and earlier are affected; the default configuration is unaffected
- Distribution packages: affected versions are marked by Azure Linux, Ubuntu and Debian; exact distribution fixed versions are unknown
Fixed in
- Apache Thrift 0.25.0
Workaround
Unknown. No vendor-documented workaround is known. Limiting the size of compressed input from untrusted clients and capping decompressed sizes in application code are general defensive measures.
Exploitation
- CISA SSVC assessment: exploitation none, automatable yes, technical impact partial
- No reports of active exploitation found
- No public proof-of-concept found
- EPSS 0.00426 (PT); CISA KEV status not checked
Our recommendation
- Upgrade Go applications to github.com/apache/thrift v0.25.0 and rebuild them
- Check software inventories and SBOMs for Thrift versions below 0.25.0, especially internet-facing Go services
- Check distribution security trackers for fixed package versions
- Monitor for availability problems in affected services
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
