Security Bulletin: Multiple vulnerabilities in Apache HTTP Server affect IBM Cognos Business Intelligence

Summary

This bulletin addresses several security vulnerabilities in Apache HTTP Server that are fixed in IBM Cognos Business Intelligence.

Vulnerability Details

CVEID: CVE-2016-0736 DESCRIPTION: Apache HTTPD could allow a remote attacker to obtain sensitive information, caused by an error in mod_session_crypto. By sending specially crafted data, a remote attacker could exploit this vulnerability via the POODLE (Padding Oracle On Downgraded Legacy Encryption) attack to gain access and modify session data.
CVSS Base Score: 5.4
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/119918&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N)

CVEID: CVE-2016-2161 DESCRIPTION: Apache HTTPD is vulnerable to a denial of service, caused by an error in mod_auth_digest. By sending specially crafted data, a remote attacker could exploit this vulnerability to cause the server to crash.
CVSS Base Score: 5.3
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/119919&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID: CVE-2016-8743 DESCRIPTION: Apache HTTPD is vulnerable to HTTP response splitting attacks, caused by improper validation of user-supplied input. A remote attacker could exploit this vulnerability to inject arbitrary HTTP headers and cause the server to return a split response, once the URL is clicked. This would allow the attacker to perform further attacks, such as Web cache poisoning or cross-site scripting, and possibly obtain sensitive information.
CVSS Base Score: 6.1
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/119917&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N)

CVEID: CVE-2018-1312 DESCRIPTION: Apache HTTPD could allow a remote attacker to bypass security restrictions, caused by the failure to properly generate an HTTP Digest authentication nonce when generating an HTTP Digest authentication challenge. An attacker could exploit this vulnerability to replay HTTP requests across servers without detection.
CVSS Base Score: 5.3
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/140853&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)

CVEID: CVE-2016-4975 DESCRIPTION: Apache HTTP Server is vulnerable to HTTP response splitting attacks, caused by a CRLF injection with the use of mod_userdir. A remote attacker could exploit this vulnerability to inject arbitrary HTTP headers and cause the server to return a split response, once the URL is clicked. This would allow the attacker to perform further attacks, such as Web cache poisoning or cross-site scripting, and possibly obtain sensitive information.
CVSS Base Score: 6.1
