Apache Thrift: Uncaught exception in Perl bindings causes denial of service
Summary
Apache Thrift's Perl bindings contain an uncaught exception. When a single connection fails, the Perl server ends its serve() loop. A remote attacker can trigger this without authentication or user interaction, causing a denial of service. Exposure applies to Perl Thrift servers reachable over the network.
Affected
- Apache Thrift before 0.25.0, Perl bindings
- Distribution builds of perl-thrift below the fixed version (Azure Linux: below 0.25.0-1)
Fixed in
- Apache Thrift 0.25.0, which also fixes several other issues in the language bindings
- Red Hat: perl-thrift 0.25.0-0.1.hum1
Workaround
- Unknown: no vendor workaround documented.
- Until patched, restrict network access to the Thrift service port.
- Run Perl Thrift servers under a supervisor that restarts them after a failure.
Exploitation
- Not listed in CISA KEV.
- No public exploit or proof of concept known.
- EPSS: 0.00426 (low).
- CISA SSVC: exploitation none, not automatable.
Our recommendation
- Check whether Perl Thrift servers or perl-thrift packages are in use.
- Upgrade to Apache Thrift 0.25.0 or a vendor build with the fix during regular maintenance.
- Escalate if the service is internet-facing or business-critical.
- Monitor the service for crashes or restarts.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
