CVE-2006-3747: Off-by-one error in the ldap scheme handling in the Rewrite module (mod_rewrite) in Apache 1.3 from 1.3.28,...

Off-by-one error in the ldap scheme handling in the Rewrite module (mod_rewrite) in Apache 1.3 from 1.3.28, 2.0.46 and other versions before 2.0.59, and 2.2, when RewriteEngine is enabled, allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via crafted URLs that are not properly handled using certain rewrite rules.

Security readout for executives and security teams

CVE-2006-3747 is an old Apache HTTP Server mod_rewrite flaw. If vulnerable legacy Apache versions have RewriteEngine enabled with certain rewrite rules, a crafted URL can crash the server and may allow code execution. Business urgency depends on whether any legacy Apache instances remain exposed. Exposure is most likely on legacy Apache HTTP Server installations still running affected 1.3, 2.0, or 2.2 branches with mod_rewrite and RewriteEngine enabled. Internet-facing web servers using rewrite rules involving affected ldap scheme handling deserve priority review. Treat this as high priority only where legacy Apache remains in service. Modern estates may have little exposure, but an affected internet-facing server combines remote crash risk with possible code execution, which justifies prompt inventory and remediation. Mitigation focus: Inventory Apache HTTP Server versions and mod_rewrite usage across all environments.; Upgrade affected Apache versions according to Apache or operating-system vendor guidance.; Review RewriteEngine-enabled virtual hosts and rewrite rules for ldap scheme handling..
