CVE-2021-47779 — Dolibarr ERP-CRM 14.0.2 - Stored Cross-Site Scripting (XSS) / Privilege Escalation

Dolibarr ERP-CRM 14.0.2 contains a stored cross-site scripting vulnerability in the ticket creation module that allows low-privilege users to inject malicious scripts. Attackers can craft a specially designed ticket message with embedded JavaScript that triggers when an administrator copies the text, potentially enabling privilege escalation.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.4% (30-day exploitation probability)+4
  • Technical severity (medium)+3
  • CISA SSVC: exploitation "poc"+5

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Dolibarr CRM, Dolibarr Dolibarr Erp/crm).
  2. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  3. Exploitation requires user interaction: tighten email/web filtering and warn affected users.
  4. Search available logs for exploit probes matching the vulnerability class (cross-site scripting), errors and authentication anomalies.

What should defenders know first?

CVE-2021-47779 is "Dolibarr ERP-CRM 14.0.2 - Stored Cross-Site Scripting (XSS) / Privilege Escalation", rated Medium. It affects CRM (Dolibarr); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 5.4 describes technical severity. EPSS 0.35% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
