Vulnerability Details
CVEID: CVE-2022-28614
DESCRIPTION: Apache HTTP Server could allow a remote attacker to obtain sensitive information, caused by an error in the ap_rwrite() function. By reflecting very large input using ap_rwrite() or ap_rputs(), such as with mod_luas r:puts() function, an attacker could exploit this vulnerability to read unintended memory.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/228342 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)
CVEID: CVE-2022-28615
DESCRIPTION: Apache HTTP Server could allow a remote attacker to obtain sensitive information, caused by a read beyond bounds in ap_strcmp_match() when provided with an extremely large input buffer. An attacker could exploit this vulnerability to crash or disclose information.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/228340 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L)
CVEID: CVE-2022-29404
DESCRIPTION: Apache HTTP Server is vulnerable to a denial of service, caused by no default limit on possible input size. By sending a specially crafted request to a lua script that calls r:parsebody(0), an attacker could exploit this vulnerability to cause a denial of service.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/228339 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-2022-26377
DESCRIPTION: Apache HTTP Server is vulnerable to HTTP request smuggling, caused by an inconsistent Interpretation of HTTP Requests vulnerability in mod_proxy_ajp. An attacker could exploit this vulnerability to smuggle requests to the AJP server it forwards requests to.
CVSS Base score: 7.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/228343 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-2022-31813
DESCRIPTION: Apache HTTP Server could allow a remote attacker to bypass security restrictions, caused by the failure to send the X-Forwarded-* headers to the origin server based on client side Connection header hop-by-hop mechanism. An attacker could exploit this vulnerability to bypass IP based authentication on the origin server/application.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/228337 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)
CVEID: CVE-2022-30556
DESCRIPTION: Apache HTTP Server could allow a remote attacker to obtain sensitive information, caused by an error in mod_lua with websockets. An attacker could exploit this vulnerability to return lengths to applications calling r:wsread() that point past the end of the storage allocated for the buffer.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/228336 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)
