![]() ![]() This is particularly true if you are attempting to roll your on data validation routines. As with the other prevention techniques a positive validation scheme, or white-list, is always preferred over a black-list approach. In general, mitigation for all injection vulnerabilities starts with input validation. BUGZILLA LDAP CODEVulnerable Perl code use Bugzilla::Util use Net::LDAP sub _bz_search_params Specifically, when a user submits his credentials, no validation check is performed and the username is passed as is to create the filter which will be passed to $self->ldap->search(). Up until November 1, 2012, a vulnerability existed in Bugzilla that allowed an attacker to inject arbitrary data into an LDAP directory via a crafted login attempt. BUGZILLA LDAP SOFTWAREBugzilla, like many software products, supports integration with external authentication mechanisms such as LDAP. ![]() The same advanced exploitation techniques leveraged in SQL Injection can be similarly applied in LDAP injection.įor the purpose of illustration, let’s examine a public LDAP injection vulnerability ( CVE-2012-3981) that was recently identified in the popular software management tool, Bugzilla. This can result in the execution of arbitrary commands such as granting permissions to unauthorized queries as well as content alterations within the LDAP tree. Closely, resembling SQL injection, LDAP injection occurs when LDAP statements are constructed with unverified user-supplied data. LDAP injection occurs when an application fails to neutralize characters that have special meaning in LDAP. BUGZILLA LDAP HOW TOThis series of blog posts will teach you how to identify and prevent this vulnerability from occurring. Query and command injections are some of the most devastating classes of vulnerabilities in existence. ( /bugzilla/editparams.cgisectionauth) Now scroll down, until you reach the userverifyclass area. Our team will help you understand your organization's current security posture within an established, objective framework so you can be strategic when growing your security program. To successfully connect your Bugzilla system with the UCS LDAP, login into Bugzilla with your administration account and visit the User Authentication tab in the core parameter settings.
