Huawei EulerOS: Security Advisory for httpd (EulerOS-SA-2019-2593)

Published: 2020-01-23 13:07:52
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:M/Au:N/C:N/I:N/A:P

Summary:
The remote host is missing an update for the Huawei EulerOS 'httpd' Linux Distribution Package(s) announced via the EulerOS-SA-2019-2593 advisory.

Detection Method:
Checks if a vulnerable Linux Distribution Package version is present on the target host.

Technical Details:
A specially crafted request could have crashed the Apache HTTP Server prior to version 2.4.30, due to an out of bound access after a size limit is reached by reading the HTTP header. This vulnerability is considered very hard if not impossible to trigger in non-debug mode (both log and build level), so it is classified as low risk for common server usage.(CVE-2018-1301) In Apache httpd 2.4.0 to 2.4.29, when mod_session is configured to forward its session data to CGI applications (SessionEnv on, not the default), a remote user may influence their content by using a 'Session' header. This comes from the 'HTTP_SESSION' variable name used by mod_session to forward its data to CGIs, since the prefix 'HTTP_' is also used by the Apache HTTP Server to pass HTTP header fields, per CGI specifications.(CVE-2018-1283)

Affected Versions:
'httpd' Linux Distribution Package(s) on Huawei EulerOS V2.0SP3.

Recommendations:
Please install the updated Linux Distribution Package(s).

Solution Type:
Vendor Patch

Detection Type:
Linux Distribution Package

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
