New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote web server is affected by multiple vulnerabilities.
DescriptionThe version of IBM HTTP Server running on the remote host is affected by multiple vulnerabilities, as follows:
- Race condition in the mod_status module in the Apache HTTP Server before 2.4.10 allows remote attackers to cause a denial of service (heap-based buffer overflow), or possibly obtain sensitive credential information or execute arbitrary code, via a crafted request that triggers improper scoreboard handling within the status_handler function in modules/generators/mod_status.c and the lua_ap_scoreboard_worker function in modules/lua/lua_request.c. (CVE-2014-0226)
- The mod_cgid module in the Apache HTTP Server before 2.4.10 does not have a timeout mechanism, which allows remote attackers to cause a denial of service (process hang) via a request to a CGI script that does not read from its stdin file descriptor. (CVE-2014-0231)
- The deflate_in_filter function in mod_deflate.c in the mod_deflate module in the Apache HTTP Server before 2.4.10, when request body decompression is enabled, allows remote attackers to cause a denial of service (resource consumption) via crafted request data that decompresses to a much larger size. (CVE-2014-0118)
- The mod_headers module in the Apache HTTP Server 2.2.22 allows remote attackers to bypass 'RequestHeader unset' directives by placing a header in the trailer portion of data sent with chunked transfer coding.
NOTE: the vendor states 'this is not a security issue in httpd as such.' (CVE-2013-5704)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
SolutionUpgrade to IBM HTTP Server version 22.214.171.124, 126.96.36.199, 188.8.131.52 or later. Alternatively, upgrade to the minimal fix pack level required by the interim fix and then apply Interim Fix PI22070.
