An issue was discovered in Open Ticket Request System (OTRS) 6.0.x before 6.0.12. An attacker could send an e-mail message with a malicious link to an OTRS system or an agent. If a logged-in agent opens this link, it could cause the execution of JavaScript in the context of OTRS.
Improper Authorization vulnerability in OTRS AG OTRS 8 (Websocket API backend) allows any as Agent authenticated attacker to track user behaviour and to gain live insight into overall system usage. User IDs can easily be correlated with real names e. g. via ticket histories by any user. (Fuzzing for garnering other adjacent user/sensitive data). Subscribing to all possible push events could also lead to performance implications on the server side, depending on the size of the installation and the number of active users. (Flooding)This issue affects OTRS: from 8.0.X before 8.0.32.
An attacker who is logged into OTRS as an user with privileges to create and change customer user data may manipulate the CustomerID field to execute JavaScript code that runs immediatly after the data is saved.The issue onlyoccurs if the configuration for AdminCustomerUser::UseAutoComplete was changed before. This issue affects OTRS: from 7.0.X before 7.0.47, from 8.0.X before 8.0.37; ((OTRS)) Community Edition: from 6.0.X through 6.0.34.
The functions to fetch e-mail via POP3 or IMAP as well as sending e-mail via SMTP use OpenSSL for static SSL or TLS based communication. As the SSLgetverifyresult() function is not used the certificated is trusted always and it can not be ensured that the certificate satisfies all necessary security requirements.
This could allow an attacker to use an invalid certificate to claim to be a trusted host, use expired certificates, or conduct other attacks that could be detected if the certificate is properly validated.
This issue affects OTRS: from 7.0.X before 7.0.47, from 8.0.X before 8.0.37; ((OTRS)) Community Edition: from 6.0.X through 6.0.34.
An issue was discovered in Open Ticket Request System (OTRS) 5.x before 5.0.34, 6.x before 6.0.16, and 7.x before 7.0.4. An attacker who is logged into OTRS as an agent or a customer user may upload a carefully crafted resource in order to cause execution of JavaScript in the context of OTRS. This is related to Content-type mishandling in Kernel/Modules/PictureUpload.pm.
Improper Neutralization of commands allowed to be executed via OTRS System Configuration e.g. SchedulerCronTaskModule using UnitTests modules allows any authenticated attacker with admin privileges local execution of Code.This issue affects OTRS: from 7.0.X before 7.0.45, from 8.0.X before 8.0.35; ((OTRS)) Community Edition: from 6.0.1 through 6.0.34.
