CyberRota Analysis

AI-Generated

Multiple versions of Spring Security are vulnerable due to the use of standard string equality for comparing security-sensitive values, which can lead to timing attacks. This vulnerability allows an attacker to infer information about the correct value based on the time taken to respond to incorrect inputs. Organizations using affected versions of Spring Security should prioritize patching to mitigate potential exploitation risks.

Original NVD Description

Several components in Spring Security compare security-sensitive values using standard string equality (String.equals()) rather than a constant-time comparison. Because String.equals() returns as soon as it finds a differing character, the time taken to reject an incorrect value is proportional to the number of leading characters that match the expected value. Spring Security 7.1.0 Spring Security 7.0.0 - 7.0.6 Spring Security 6.5.0 - 6.5.11 Spring Security 6.4.0 - 6.4.18 Spring Security 5.8.0 - 5.8.27 Spring Security 5.7.0 - 5.7.25
