CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:NCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2023-48104 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Alinto Sogo. Its CVSS base score is 6.1 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Protocol or Service Impersonation (T1001.003); ranked in the top 37% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
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.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover missing or incorrect input neutralization through targeted web-application tests.
Input validation directly enforces neutralization of untrusted data before it reaches web output generation.
Output filtering can catch or sanitize unneutralized script content before it is served to users.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure SDLC practices directly target introduction of XSS via coding standards/testing (mostly), yet the single broad outcome leaves many specific neutralization vectors unaddressed (partial).
Patching and EOL replacement can remediate known XSS instances in libraries or frameworks (partial) but do nothing to enforce input neutralization in application code (none).

A.5.6 only promotes membership in groups to improve knowledge, receive alerts, and share information; it performs no action that stops XSS exploitation (or even the underlying neutralization defect) and is a pure dependency for other controls per the owner's labeling rule.
