Vulnerabilidad · Publicado 12/10/2026
Una vulnerabilidad de traversal de rutas en la funcionalidad SendSupportBundle de OTRS permite que administradores autenticados eliminen archivos fuera del directorio previsto en servidores de soporte técnico. El riesgo es alta (CVSS 8.7) en versiones anteriores a OTRS 7, donde los permisos efectivos del servidor web amplían el acceso. Empresas de helpdesk y soporte en LATAM que usen OTRS deben evaluar su exposición inmediatamente.
A path traversal vulnerability in the OTRS SendSupportBundle functionality allows an authenticated administrator to reference file paths outside the intended directory. This may allow files accessible to the OTRS application process to be deleted. The vulnerability does not bypass operating system file permissions. On OTRS versions prior to OTRS 7, the effective permissions of the web server process are relevant. Starting with OTRS 7, access is limited by the permissions of the dedicated OTRS user. Files with overly permissive ownership or file system permissions may therefore also be affected. The affected functionality may additionally attempt to include controlled files in a support bundle. However, support bundles are sent to a predefined OTRS support address, and direct disclosure of arbitrary files to the attacker has not been demonstrated. An attacker therefore requires valid administrative access to exploit the vulnerable functionality. The primary demonstrated impact is the deletion of files outside the intended directory within the effective permissions of the OTRS application process. This issue affects OTRS: * 7.0.X * 8.0.X * 2023.X * 2024.X * 2025.X * 2026.X before 2026.7.X Please note that ((OTRS)) Community Edition 6.x and before are vulnerable. Products based on the ((OTRS)) Community Edition also very likely to be affected
