The AgentTicketForward feature in Open Ticket Request System (OTRS) before 2.4.7 does not properly remove inline images from HTML e-mail messages, which allows remote attackers to obtain potentially sensitive image information in opportunistic circumstances by reading a forwarded message in a standard e-mail client.
Open Ticket Request System (OTRS) before 2.3.6 does not properly handle e-mail messages in which the From line contains UTF-8 characters associated with diacritical marks and an invalid charset, which allows remote attackers to cause a denial of service (duplicate tickets and duplicate auto-responses) by sending a crafted message to a POP3 mailbox.
Open Ticket Request System (OTRS) before 2.3.5 does not properly disable hidden permissions, which allows remote authenticated users to bypass intended queue access restrictions in opportunistic circumstances by visiting a ticket, related to a certain ordering of permission-set and permission-remove operations involving both hidden permissions and other permissions.
The (1) AgentInterface and (2) CustomerInterface components in Open Ticket Request System (OTRS) before 3.0.6 place cleartext credentials into the session data in the database, which makes it easier for context-dependent attackers to obtain sensitive information by reading the _UserLogin and _UserPW fields.
webscript.pl in Open Ticket Request System (OTRS) 2.3.4 and earlier allows remote attackers to execute arbitrary commands via unspecified vectors, related to a "command injection vulnerability."
Cross-site scripting (XSS) vulnerability in AgentTicketZoom in OTRS 2.4.x before 2.4.9, when RichText is enabled, allows remote attackers to inject arbitrary web script or HTML via JavaScript in an HTML e-mail.
Open Ticket Request System (OTRS) 2.3.x before 2.3.6 and 2.4.x before 2.4.8 does not properly handle the matching of Perl regular expressions against HTML e-mail messages, which allows remote attackers to cause a denial of service (CPU consumption) via a large message, a different vulnerability than CVE-2010-2080.
Multiple cross-site scripting (XSS) vulnerabilities in Open Ticket Request System (OTRS) 2.3.x before 2.3.6 and 2.4.x before 2.4.8 allow remote authenticated users to inject arbitrary web script or HTML via unspecified vectors.
Multiple SQL injection vulnerabilities in Kernel/System/Ticket.pm in OTRS-Core in Open Ticket Request System (OTRS) 2.1.x before 2.1.9, 2.2.x before 2.2.9, 2.3.x before 2.3.5, and 2.4.x before 2.4.7 allow remote authenticated users to execute arbitrary SQL commands via unspecified vectors.
The SOAP interface in OTRS 2.1.x before 2.1.8 and 2.2.x before 2.2.6 allows remote attackers to "read and modify objects" via SOAP requests, related to "Missing security checks."
