When adding attachments to ticket comments, another user can add attachments as well impersonating the orginal user. The attack requires a logged-in other user to know the UUID. While the legitimate user completes the comment, the malicious user can add more files to the comment. This issue affects OTRS: from 7.0.X through 7.0.48, from 8.0.X through 8.0.37, from 2023.X through 2023.1.1.

Insertion of debug information into log file during building the elastic search index allows reading of sensitive information from articles.This issue affects OTRS: from 7.0.X through 7.0.48, from 8.0.X through 8.0.37, from 2023.X through 2023.1.1.

Improper Input Validation vulnerability in the upload functionality for user avatars allows functionality misuse due to missing check of filetypes. This issue affects OTRS: from 7.0.X through 7.0.48, from 8.0.X through 8.0.37, from 2023 through 2023.1.1.

A Vulnerability in OTRS AgentInterface and ExternalInterface allows the reading of plain text passwords which are send back to the client in the server response- This issue affects OTRS: from 8.0.X through 8.0.37.

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 SSL_get_verify_result() 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 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 loading of external images is not blocked, even if configured, if the attacker uses protocol-relative URL in the payload. This can be used to retreive the IP of the user.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 improper privilege check in the OTRS ticket move action in the agent interface allows any as agent authenticated attacker to to perform a move of an ticket without the needed permission. This issue affects OTRS: from 8.0.X before 8.0.35.

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.

Improper Input Validation vulnerability in OTRS AG OTRS (ACL modules), OTRS AG ((OTRS)) Community Edition (ACL modules) allows Local Execution of Code. When creating/importing an ACL it was possible to inject code that gets executed via manipulated comments and ACL-names This issue affects OTRS: from 7.0.X before 7.0.42, from 8.0.X before 8.0.31; ((OTRS)) Community Edition: from 6.0.1 through 6.0.34.

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.
