Security Bulletin: IBM Security SiteProtector System is affected by multiple Apache HTTP Server Vulnerabilities

Description

## Summary Apache HTTP Server provides HTTP services for SiteProtector. IBM Security SiteProtector System has addressed the following vulnerabilities in a Core express update: ## Vulnerability Details **CVEID: **[CVE-2022-22719](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-22719>) **DESCRIPTION: **Apache HTTP Server is vulnerable to a denial of service. By using a specially crafted request body to read a random memory area, a remote attacker could exploit this vulnerability to cause the process to crash. CVSS Base score: 5.3 CVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/221667](<https://exchange.xforce.ibmcloud.com/vulnerabilities/221667>) for the current score. CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L) **CVEID: **[CVE-2022-22720](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-22720>) **DESCRIPTION: **Apache HTTP Server is vulnerable to HTTP request smuggling, caused by the failure to close inbound connection when errors are encountered discarding the request body. An attacker could exploit this vulnerability to poison the web cache, bypass web application firewall protection, and conduct XSS attacks. CVSS Base score: 7.3 CVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/221668](<https://exchange.xforce.ibmcloud.com/vulnerabilities/221668>) for the current score. CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L) **CVEID: **[CVE-2022-22721](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-22721>) **DESCRIPTION: **Apache HTTP Server is vulnerable to a buffer overflow, caused by an integer overflow. If LimitXMLRequestBody is set to allow request bodies larger than 350MB, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash. CVSS Base score: 7.3 CVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/221666](<https://exchange.xforce.ibmcloud.com/vulnerabilities/221666>) for the current score. CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L) **CVEID: **[CVE-2021-44790](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-44790>) **DESCRIPTION: **Apache HTTP Server is vulnerable to a buffer overflow, caused by improper bounds checking in the mod_lua multipart parser called from Lua scripts). By sending a specially crafted request, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash. CVSS Base score: 9.8 CVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/215686](<https://exchange.xforce.ibmcloud.com/vulnerabilities/215686>) for the current score. CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) **CVEID: **[CVE-2021-44224](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-44224>) **DESCRIPTION: **Apache HTTP Server is vulnerable to a denial of service or server-side request forgery. By sending a specially crafted URI to httpd configured as a forward proxy, an attacker could exploit this vulnerability to cause a NULL pointer dereference. By sending a specially crafted URI to configurations mixing forward and reverse proxy declarations, an attacker could allow for requests to be directed to a declared Unix Domain Socket endpoint. CVSS Base score: 8.2 CVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/215719](<https://exchange.xforce.ibmcloud.com/vulnerabilities/215719>) for the current score.
