Apache 2.4.x < 2.4.33 Multiple Vulnerabilities
Medium Nessus Plugin ID 108758
SynopsisThe remote web server is affected by multiple vulnerabilities.
DescriptionAccording to its banner, the version of Apache running on the remote host is 2.4.x prior to 2.4.33. It is, therefore, affected by the following vulnerabilities:
- An out-of-bounds write flaw exists within the derive_codepage_from_lang() function of the modules/aaa/mod_authnz_ldap.c script due to improper handling of 'Accept-Language' header values that are less than two-bytes. A remote attacker, with a specially crafted request, could potentially crash the process. (CVE-2017-15710)
- A ACL bypass flaw exists within the ap_rgetline_core() function of the server/protocol.c script due to improper handling of <FilesMatch> expressions. A remote attacker could potentially bypass restrictions an upload a file. (CVE-2017-15715)
- A data tampering flaw exists in the session_fixups() function of the modules/session/mod_session.c script when forwarding mod_session data to CGI applications. A remote attacker, with a specially crafted request, could potentially tamper with the mod_session data of the CGI application. (CVE-2018-1283)
- An out-of-bound read flaw exists when hitting a size limit while handling HTTP headers. A remote attacker, with a specially crafted request, could crash the process. (CVE-2018-1301)
- A use-after-free flaw exists when handling the HTTP/2 stream shutdown. A remote attacker could potentially write to already freed memory and crash the process. (CVE-2018-1302)
- An out-of-bounds read flaw exists in the read_table() function of the modules/cache/mod_cache_socache.c script when handling empty headers. A remote attacker, with a specially crafted request, could potentially crash the process. (CVE-2018-1303)
- A flaw exists within the modules/aaa/mod_auth_digest.c script due to improperly generating nonce when sending HTTP Digest Authentication challenges. A remote attacker could potentially conduct replay attacks against the server. (CVE-2018-1312)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
SolutionUpgrade to Apache version 2.4.33 or later.
