CERTFR-2020-AVI-777
Vulnerability from certfr_avis
De multiples vulnérabilités ont été découvertes dans Drupal core. Elles permettent à un attaquant de provoquer une atteinte à l'intégrité des données et une atteinte à la confidentialité des données.
Solution
Se référer au bulletin de sécurité de l'éditeur pour l'obtention des correctifs (cf. section Documentation).
Contournement provisoire
L'éditeur propose comme mesure de contournement pour ces vulnérabilités de limiter aux utilisateurs de confiance le téléchargement des fichiers .tar, .tar.gz, .bz2 et .tlz.
- Drupal 9.x versions antérieures à 9.0.9
- Drupal 8.9.x versions antérieures à 8.9.10
- Drupal 8.8.x versions antérieures à 8.8.12
- Drupal 7.x versions antérieures à 7.75
L'éditeur ne maintient plus les versions 8 antérieures à 8.8.x. Les utilisateurs d'une version obsolète doivent préalablement mettre à jour Drupal pour bénéficier des correctifs de sécurité.
