Deeper analysis
Alinto SOGo versions prior to 5.9.1 contain an HTML injection vulnerability tracked as CVE-2023-48104 and assigned CWE-79. The flaw received a CVSS 3.1 score of 6.1 with the vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N, indicating a remotely exploitable issue that requires user interaction but needs no authentication.
An unauthenticated attacker can supply crafted HTML content that is rendered in a victim's browser session when the victim interacts with a malicious link or message. Successful exploitation allows the attacker to execute arbitrary script in the context of the affected SOGo instance, potentially leading to session hijacking, data exfiltration, or actions performed on behalf of the user within the application.
The referenced commit 7481ccf37087c3f456d7e5a844da01d0f8883098 in the Alinto/sogo repository addresses the issue; administrators should upgrade to version 5.9.1 or later. Public proof-of-concept material is available, and the EPSS score has remained at 0.1784 without a documented increase after disclosure.
