Description
This security bulletin contains information about 1 security vulnerability.
1) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2020-7238)
The vulnerability allows a remote attacker to perform HTTP request smuggling attack.
The vulnerability exists due to improper input validation when processing a whitespace before the colon in HTTP headers (e.g. "Transfer-Encoding : chunked") and a later Content-Length header. A remote attacker can send a specially crafted HTTP request and perform HTTP request smuggling attack.
This issue exists because of an incomplete fix for CVE-2019-16869 (SB2019092616).
