CWE ID Description
CWE-121 A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
CWE-190 The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.

Executive Summary

This vulnerability involves a stack-based buffer overflow or integer overflow in Apache Thrift's PHP bindings. These flaws can lead to memory corruption or unexpected behavior when processing malicious input.

Detection Guidance

This vulnerability affects Apache Thrift PHP bindings before version 0.25.0. Detection involves checking the installed version of Apache Thrift. Use the command 'thrift --version' to verify the version. If the version is below 0.25.0, the system is vulnerable.

Impact Analysis

Compliance Impact

This vulnerability could lead to data breaches or unauthorized access, violating GDPR (data protection) and HIPAA (health data privacy). Non-compliance may result in legal penalties or reputational damage.

Mitigation Strategies

Upgrade Apache Thrift to version 0.25.0 or later to address the Stack-based Buffer Overflow and Integer Overflow vulnerabilities.
