HighCVSS 7.3Exploitation Probability (EPSS)
Low risk48th percentile - higher than 48% of all known CVEs
Summary
Apache Thrift before version 0.23.0 improperly validates TLS certificates, allowing host mismatch. An attacker can exploit this for man-in-the-middle attacks.
Risk Assessment
The organization is at risk of eavesdropping or modification of communication between services using Thrift, potentially leading to data leakage.
Recommendation
Upgrade Apache Thrift to version 0.23.0 or later.
