Possible DoS via SQL Box

A vulnerability in the SQL Box in the admin interface of OTRS leads to an uncontrolled resource consumption leading to a DoS against the webserver. will be killed by the systemThis issue affects OTRS:  * 7.0.X * 8.0.X * 2023.X * 2024.X * 2025.X * 2026.X before 2026.3.X

Multiple SQL injection vulnerabilities in index.pl in Open Ticket Request System (OTRS) 1.0.0 through 1.3.2 and 2.0.0 through 2.0.3 allow remote attackers to execute arbitrary SQL commands and bypass authentication via the (1) user parameter in the Login action, and remote authenticated users via the (2) TicketID and (3) ArticleID parameters of the AgentTicketPlain action.

Open Ticket Request System (OTRS) 1.0.0 through 1.3.2 and 2.0.0 through 2.0.3, when AttachmentDownloadType is set to inline, renders text/html e-mail attachments as HTML in the browser when the queue moderator attempts to download the attachment, which allows remote attackers to execute arbitrary web script or HTML. NOTE: this particular issue is referred to as XSS by some sources.

Multiple cross-site scripting (XSS) vulnerabilities in index.pl in Open Ticket Request System (OTRS) 1.0.0 through 1.3.2 and 2.0.0 through 2.0.3 allow remote authenticated users to inject arbitrary web script or HTML via (1) hex-encoded values in the QueueID parameter and (2) Action parameters.

Upload of files outside application directory

The file upload feature in OTRS and ((OTRS)) Community Edition has a path traversal vulnerability. This issue permits authenticated agents or customer users to upload potentially harmful files to directories accessible by the web server, potentially leading to the execution of local code like Perl scripts. This issue affects OTRS: from 7.0.X through 7.0.49, 8.0.X, 2023.X, from 2024.X through 2024.3.2; ((OTRS)) Community Edition: from 6.0.1 through 6.0.34.

Passwords are written to Admin Log Module

Passwords of agents and customers are displayed in plain text in the OTRS admin log module if certain configurations regarding the authentication sources match and debugging for the authentication backend has been enabled. This issue affects: * OTRS from 7.0.X through 7.0.50 * OTRS 8.0.X * OTRS 2023.X * OTRS from 2024.X through 2024.5.X * ((OTRS)) Community Edition: 6.0.x Products based on the ((OTRS)) Community Edition also very likely to be affected

Possible user enumeration

A vulnerability in the External Interface of OTRS allows conclusions to be drawn about the existence of user accounts through different HTTP response codes and messages. This enables an attacker to systematically identify valid email addresses. This issue affects: * OTRS 7.0.X * OTRS 8.0.X * OTRS 2023.X * OTRS 2024.X * OTRS 2025.X

Unnecessary data is written to log if issues during indexing occurs

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.

DoS attack using email

An external attacker is able to send a specially crafted email (with many recipients) and trigger a potential DoS of the system

Information exposure of template content due to missing check of permissions

Article template contents with sensitive data could be accessed from agents without permissions.

Open Ticket Request System (OTRS) 4.0.x before 4.0.28, 5.0.x before 5.0.26, and 6.0.x before 6.0.3, when cookie support is disabled, might allow remote attackers to hijack web sessions and consequently gain privileges via a crafted email.

Code injection exists in Kernel/System/Spelling.pm in Open Ticket Request System (OTRS) 5 before 5.0.24, 4 before 4.0.26, and 3.3 before 3.3.20. In the agent interface, an authenticated remote attacker can execute shell commands as the webserver user via URL manipulation.

Open Ticket Request System (OTRS) 3.3.9 has XSS in index.pl?Action=AgentStats requests, as demonstrated by OrderBy=[XSS] and Direction=[XSS] attacks. NOTE: this CVE may have limited relevance because it represents a 2017 discovery of an issue in software from 2014. The 3.3.20 release, for example, is not affected.

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.

In Open Ticket Request System (OTRS) 3.3.x before 3.3.18, 4.x before 4.0.25, and 5.x before 5.0.23, remote authenticated users can leverage statistics-write permissions to gain privileges via code injection.

In the Agent Frontend in Open Ticket Request System (OTRS) 3.3.x through 3.3.18, with a crafted URL it is possible to gain information like database user and password.

In Open Ticket Request System (OTRS) through 3.3.20, 4 through 4.0.26, 5 through 5.0.24, and 6 through 6.0.1, an attacker who is logged in as a customer can use the ticket search form to disclose internal article information of their customer tickets.

In OTRS 6.0.x up to and including 6.0.1, OTRS 5.0.x up to and including 5.0.24, and OTRS 4.0.x up to and including 4.0.26, an attacker who is logged into OTRS as an agent can manipulate form parameters (related to PGP) and execute arbitrary shell commands with the permissions of the OTRS or web server user.

In Open Ticket Request System (OTRS) 3.3.x through 3.3.16, 4.x through 4.0.23, and 5.x through 5.0.19, an attacker with agent permission is capable of opening a specific URL in a browser to gain administrative privileges / full access. Afterward, all system settings can be read and changed. The URLs in question contain index.pl?Action=Installer with ;Subaction=Intro or ;Subaction=Start or ;Subaction=System appended at the end.

SQL Injection via OTRS Search API

Improper Input Validation vulnerability in OTRS AG OTRS, OTRS AG ((OTRS)) Community Edition allows SQL Injection via TicketSearch Webservice This issue affects OTRS: from 7.0.1 before 7.0.40 Patch 1, from 8.0.1 before 8.0.28 Patch 1; ((OTRS)) Community Edition: from 6.0.1 through 6.0.34.
