CVE-2006-20001

CVSS v2.0

7.8

High

VectorAV:N/AC:L/Au:N/C:N/I:N/A:C
Name of the Vulnerable Software and Affected Versions: Apache HTTP Server versions 2.4.54 and earlier
Description: A carefully crafted If: request header can cause a memory read, or write of a single zero byte, in a pool (heap) memory location beyond the header value sent. This could cause the process to crash. The issue is also related to a buffer overflow in the mod dav module, which can allow a remote attacker to cause a denial of service.
Recommendations: For Apache HTTP Server versions 2.4.54 and earlier, update to a version later than 2.4.54 to resolve the issue. As a temporary workaround, consider restricting access to the If: request header to minimize the risk of exploitation. Additionally, restricting access to the mod dav module can also help mitigate the risk of a denial of service attack.
