When OTRS uses multiple backends for user authentication (with LDAP), agents are able to login even if the account is set to invalid. This issue affects OTRS; 8.0.9 and prior versions.
Unspecified vulnerability in Kernel/Modules/AdminPackageManager.pm in OTRS-Core in Open Ticket Request System (OTRS) 2.x before 2.4.11 and 3.x before 3.0.10 allows remote authenticated administrators to read arbitrary files via unknown vectors.
The iPhoneHandle package 0.9.x before 0.9.7 and 1.0.x before 1.0.3 in Open Ticket Request System (OTRS) does not properly restrict use of the iPhoneHandle interface, which allows remote authenticated users to gain privileges, and consequently read or modify OTRS core objects, via unspecified vectors.
Open Ticket Request System (OTRS) before 2.4.4 grants ticket access on the basis of single-digit substrings of the CustomerID value, which allows remote authenticated users to bypass intended access restrictions in opportunistic circumstances by visiting a ticket, as demonstrated by leveraging the CustomerID 12 account to read tickets that should be available only to CustomerID 1 or CustomerID 2.
Open Ticket Request System (OTRS) before 2.4.0-beta2 does not properly enforce the move_into permission setting for a queue, which allows remote authenticated users to bypass intended access restrictions and read a ticket by watching this ticket, and then selecting the ticket from the watched-tickets list.
The S/MIME feature in Open Ticket Request System (OTRS) before 2.3.4 does not configure the RANDFILE and HOME environment variables for OpenSSL, which might make it easier for remote attackers to decrypt e-mail messages that had lower than intended entropy available for cryptographic operations, related to inability to write to the seeding file.
installer.pl in Open Ticket Request System (OTRS) before 3.0.3 has an Inbound Mail Password field that uses the text type, instead of the password type, for its INPUT element, which makes it easier for physically proximate attackers to obtain the password by reading the workstation screen.
Open Ticket Request System (OTRS) before 3.0.0-beta7 does not properly restrict the ticket ages that are within the scope of a search, which allows remote authenticated users to cause a denial of service (daemon hang) via a fulltext search.
Open Ticket Request System (OTRS) before 3.0.0-beta6 adds email-notification-ext articles to tickets during processing of event-based notifications, which allows remote authenticated users to obtain potentially sensitive information by reading a ticket.
