CVE-2024-24510Network attack vector

Cross-site scripting via imported CSS directives

Published Sep 9, 2024 · Updated Nov 5, 2024

Cross-site scripting in Alinto SOGo before 5.10.0 allows remote attackers to execute web content through imported mail. The stringWithoutHTMLInjection sanitizer leaves CSS @import directives inside style elements intact, allowing imported messages to load attacker-controlled stylesheets. Exploitation requires user interaction with the imported mail; the patch establishes browser-context effects rather than server-side command execution.
