Specially crafted string in OTRS system configuration can allow the execution of any system command.

Cross-site scripting (XSS) vulnerability in Open Ticket Request System (OTRS) ITSM 3.0.x before 3.0.9, 3.1.x before 3.1.10, and 3.2.x before 3.2.7 allows remote authenticated users to inject arbitrary web script or HTML via an ITSM ConfigItem search.

Multiple SQL injection vulnerabilities in Open Ticket Request System (OTRS) Help Desk 3.0.x before 3.0.22, 3.1.x before 3.1.18, and 3.2.x before 3.2.9 allow remote authenticated users to execute arbitrary SQL commands via unspecified vectors related to Kernel/Output/HTML/PreferencesCustomQueue.pm, Kernel/System/CustomerCompany.pm, Kernel/System/Ticket/IndexAccelerator/RuntimeDB.pm, Kernel/System/Ticket/IndexAccelerator/StaticDB.pm, and Kernel/System/TicketSearch.pm.

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.

Kernel/Modules/AgentTicketWatcher.pm in Open Ticket Request System (OTRS) 3.0.x before 3.0.21, 3.1.x before 3.1.17, and 3.2.x before 3.2.8 does not properly restrict tickets, which allows remote attackers with a valid agent login to read restricted tickets via a crafted URL involving the ticket split mechanism.

Kernel/Modules/AgentTicketPhone.pm in Open Ticket Request System (OTRS) 3.0.x before 3.0.20, 3.1.x before 3.1.16, and 3.2.x before 3.2.7, and OTRS ITSM 3.0.x before 3.0.8, 3.1.x before 3.1.9, and 3.2.x before 3.2.5 does not properly restrict tickets, which allows remote attackers with a valid agent login to read restricted tickets via a crafted URL involving the ticket split mechanism.

Cross-site scripting (XSS) vulnerability in Open Ticket Request System (OTRS) 3.3.x before 3.3.16, 4.0.x before 4.0.19, and 5.0.x before 5.0.14 allows remote attackers to inject arbitrary web script or HTML via a crafted attachment.

OTRS 3.1.x before 3.1.21, 3.2.x before 3.2.16, and 3.3.x before 3.3.6 allows remote attackers to conduct clickjacking attacks via an IFRAME element.

Cross-site scripting (XSS) vulnerability in Open Ticket Request System (OTRS) 3.1.x before 3.1.21, 3.2.x before 3.2.16, and 3.3.x before 3.3.6 allows remote authenticated users to inject arbitrary web script or HTML via vectors related to dynamic fields.

Cross-site scripting (XSS) vulnerability in Open Ticket Request System (OTRS) 3.1.x before 3.1.20, 3.2.x before 3.2.15, and 3.3.x before 3.3.5 allows remote attackers to inject arbitrary web script or HTML via a crafted HTML email.

Multiple cross-site request forgery (CSRF) vulnerabilities in (1) CustomerPreferences.pm, (2) CustomerTicketMessage.pm, (3) CustomerTicketProcess.pm, and (4) CustomerTicketZoom.pm in Kernel/Modules/ in Open Ticket Request System (OTRS) 3.1.x before 3.1.19, 3.2.x before 3.2.14, and 3.3.x before 3.3.4 allow remote attackers to hijack the authentication of arbitrary users for requests that (5) create tickets or (6) send follow-ups to existing tickets.

SQL injection vulnerability in the StateGetStatesByType function in Kernel/System/State.pm in Open Ticket Request System (OTRS) 3.1.x before 3.1.19, 3.2.x before 3.2.14, and 3.3.x before 3.3.4 allows remote attackers to execute arbitrary SQL commands via vectors related to a ticket search URL.

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.
