CVE-2003-0993 - mod_access in Apache 1.3 before 1.3.30, when running big-endian 64-bit platforms, does not properly

CVE-2003-0993

Summary

mod_access in Apache 1.3 before 1.3.30, when running big-endian 64-bit platforms, does not properly parse Allow/Deny rules using IP addresses without a netmask, which could allow remote attackers to bypass intended access restrictions.

description	Henning Brauer discovered a programming error in Apache 1.3's mod_access that results in the netmasks in IP address access control rules being interpreted incorrectly on 64-bit, big-endian platforms. In some cases, this could cause a `deny from' IP address access control rule including a netmask to fail.

description	The remote host is running a version of Apache web server prior to 1.3.31. It is, therefore, affected by an access control bypass vulnerability due to a failure, on big-endian 64-bit platforms, to properly match 'allow' or 'deny' rules that contain an IP address but lack a corresponding netmask. Nessus has determined the vulnerability exists only by looking at the Server header returned by the web server running on the target. If the target is not a big-endian 64-bit platform, consider this a false positive.

description	Four security vulnerabilities were fixed with the 1.3.31 release of Apache. All of these issues have been backported and applied to the provided packages. Thanks to Ralf Engelschall of OpenPKG for providing the patches. Apache 1.3 prior to 1.3.30 did not filter terminal escape sequences from its error logs. This could make it easier for attackers to insert those sequences into the terminal emulators of administrators viewing the error logs that contain vulnerabilities related to escape sequence handling (CVE-2003-0020). mod_digest in Apache 1.3 prior to 1.3.31 did not properly verify the nonce of a client response by using an AuthNonce secret. Apache now verifies the nonce returned in the client response to check whether it was issued by itself by means of a 'AuthDigestRealmSeed' secret exposed as an MD5 checksum (CVE-2003-0987). mod_access in Apache 1.3 prior to 1.3.30, when running on big-endian 64-bit platforms, did not properly parse Allow/Deny rules using IP addresses without a netmask. This could allow a remote attacker to bypass intended access restrictions (CVE-2003-0993). Apache 1.3 prior to 1.3.30, when using multiple listening sockets on certain platforms, allows a remote attacker to cause a DoS by blocking new connections via a short-lived connection on a rarely-accessed listening socket (CVE-2004-0174). While this particular vulnerability does not affect Linux, we felt it prudent to include the fix. Update : Due to the changes in mod_digest.so, mod_perl needed to be rebuilt against the patched Apache packages in order for httpd-perl to properly load the module. The appropriate mod_perl packages have been rebuilt and are now available.

description	The remote host is affected by the vulnerability described in GLSA-200405-22 (Apache 1.3: Multiple vulnerabilities) On 64-bit big-endian platforms, mod_access does not properly parse Allow/Deny rules using IP addresses without a netmask which could result in failure to match certain IP addresses. Terminal escape sequences are not filtered from error logs. This could be used by an attacker to insert escape sequences into a terminal emulator vulnerable to escape sequences. mod_digest does not properly verify the nonce of a client response by using a AuthNonce secret. This could permit an attacker to replay the response of another website. This does not affect mod_auth_digest. On certain platforms there is a starvation issue where listening sockets fails to handle short-lived connection on a rarely-accessed listening socket. This causes the child to hold the accept mutex and block out new connections until another connection arrives on the same rarely-accessed listening socket thus leading to a denial of service. Impact : These vulnerabilities could lead to attackers bypassing intended access restrictions, denial of service, and possibly execution of arbitrary code. Workaround : There is no known workaround at this time.

description	New apache packages are available for Slackware 8.1, 9.0, 9.1, and -current to fix security issues. These include a possible denial-of-service attack as well as the ability to possible pipe shell escapes through Apache's errorlog (which could create an exploit if the error log is read in a terminal program that does not filter such escapes). We recommend that sites running Apache upgrade to the new Apache package.
