Apache Thrift PHP bindings: Denial of service via uncaught exception

Summary

The PHP bindings of Apache Thrift contain an uncaught exception flaw. In the PHP TSimpleServer, any non-transport exception terminates the entire process. A remote attacker who can reach a Thrift service built on this server can therefore crash it, causing denial of service. No authentication or user interaction is required according to the CVSS vector, and no confidentiality or integrity impact is stated.

Affected

• Apache Thrift (PHP bindings, Composer package apache/thrift) before 0.25.0
• Default configuration: unaffected

Fixed in

• Upgrade to Apache Thrift 0.25.0 or later

Workaround

Unknown.

Exploitation

• CISA SSVC: exploitation none, automatable yes, technical impact partial
• Not listed in CISA KEV
• No public proof of concept found; absence not confirmed
• No known exploitation in the wild

Our recommendation

• Check whether any PHP application uses Apache Thrift with TSimpleServer and is reachable from untrusted networks (for example with composer show apache/thrift)
• If affected, upgrade to version 0.25.0 or later; this also covers other Thrift PHP CVEs with the same fix version
• Until patched, restrict access to the Thrift endpoint to known clients using network ACLs or VPN
• Monitor the service for unexpected process terminations

Public exploits iAttack code is publicly available (PoC on GitHub, Metasploit or Exploit-DB).

PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
