CVE-2024-6423Sensitive Data Exposure via URL Parameters in Multiple WSO2 Products Allows Confidential Information Leakage
Medium 4.0
In plain English
A medium-severity improper input validation in WSO2 API Manager from WSO2. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.1% (higher than 1% of all known vulnerabilities).
Official description
The product failed to enforce validation constraints on user-supplied input in URL parameters, allowing sensitive data to be passed to flows where it was not intended to be processed. Although the product did not utilize this data, its acceptance could lead to logging. If a user mistakenly sends sensitive data via URL parameters to any flow, this data could be inadvertently logged in access logs. This has the potential to expose confidential information, compromising the security and privacy of affected systems if the product is used incorrectly.
