AnalysisAI
Resource-exhaustion denial of service in Apache Thrift's Java TSaslNonblockingServer component allows remote attackers to drive the service into an unresponsive state by consuming server resources without limit (CWE-770). All Apache Thrift releases before 0.25.0 are affected, and the CVSS:4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VA:H) confirms the attack is network-reachable and requires no credentials or user interaction once an exposed TSaslNonblockingServer endpoint is reachable; impact is confined to availability, with no confidentiality or integrity loss. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the target deploy Apache Thrift's Java TSaslNonblockingServer specifically - the non-blocking server implementation using SASL authentication - and expose it over a reachable network path. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a denial-of-service vulnerability (CWE-770, Allocation of Resources Without Limits or Throttling) in the TSaslNonblockingServer component of Apache Thrift's Java library. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patch: upgrade Apache Thrift to 0.25.0, which Apache states fixes this issue - see the advisories at https://lists.apache.org/thread/33otcgbqd27wf6qq810q56znzbomnhg1 and https://lists.apache.org/thread/shy1rrm2g383wlbdb2p7w19c868ntdjp, and rebuild any Java services pinned to older Thrift artifacts so the updated library is actually loaded. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all internet-facing and internal services running Apache Thrift and identify any that use the Java TSaslNonblockingServer class, treating every deployment on a release before 0.25.0 as affected and confirming the exact version in use. …
