Crítica

VetorAV:N/AC:L/Au:N/C:C/I:C/A:C
Name of the Vulnerable Software and Affected Versions HAProxy versions prior to 2.0.10
Description The issue is related to the HTTP/2 implementation in HAProxy, which mishandles headers. This can be exploited by an attacker to gain access to confidential data, disrupt data integrity, and cause a denial of service. The vulnerability is demonstrated by the improper handling of carriage return (CR, ASCII 0xd), line feed (LF, ASCII 0xa), and the zero character (NUL, ASCII 0x0).
Recommendations For HAProxy versions prior to 2.0.10, update to version 2.0.10 or later to resolve the issue. As a temporary workaround, consider restricting access to sensitive data and implementing additional security measures to prevent exploitation.
