The vulnerability identified as CVE-2019-17577 represents a cross-site scripting weakness within the Dolibarr ERP/CRM platform version 10.0.2. This security flaw exists within the administrative email configuration interface, specifically in the admin/mails.php?action=edit endpoint where users can manage outgoing email settings. The vulnerability manifests when an attacker can inject malicious scripts through the "Email used for error returns emails" field that corresponds to the 'Errors-To' header in sent emails. This particular configuration field lacks proper input sanitization and output encoding, creating a persistent vector for XSS attacks that can affect any user who accesses the compromised email setup page.
The technical exploitation of this vulnerability occurs through the manipulation of the Errors-To email header field within Dolibarr's email administration module. When an attacker crafts a malicious email address containing script code within the Errors-To field, this input is not properly validated or escaped before being rendered in the web interface. The vulnerability aligns with CWE-79 which classifies cross-site scripting as a critical weakness in web applications, specifically targeting the improper handling of untrusted data in web pages. The attack vector operates through the standard HTTP request mechanism where malicious input is stored and subsequently reflected back to authenticated users without appropriate sanitization, enabling the execution of arbitrary JavaScript code in their browser context.
The operational impact of CVE-2019-17577 extends beyond simple script execution as it provides attackers with the capability to hijack user sessions, steal sensitive data, and potentially escalate privileges within the Dolibarr environment. An attacker who successfully exploits this vulnerability can execute malicious scripts that may steal session cookies, redirect users to phishing sites, or even modify the application's behavior through the execution of JavaScript code. This vulnerability affects authenticated users with administrative privileges who have access to the email configuration interface, making it particularly dangerous in environments where administrators frequently manage email settings. The persistent nature of the stored XSS means that any user who views the compromised email configuration page becomes vulnerable to the injected malicious code, creating a potential attack surface that could compromise multiple users over time.
Security mitigations for CVE-2019-17577 should focus on implementing proper input validation and output encoding mechanisms within the Dolibarr application. The primary defense involves sanitizing all user inputs in the Errors-To email field through proper HTML escaping and validation routines that prevent script injection attempts. Organizations should ensure that all email address inputs are validated against standard email format requirements and that special characters are properly encoded before rendering in web interfaces. Additionally, implementing Content Security Policy (CSP) headers can provide an additional layer of protection by restricting the sources from which scripts can be executed within the application. The remediation strategy should also include regular security updates and patches from Dolibarr maintainers, as this vulnerability was addressed in subsequent releases of the platform. According to ATT&CK framework category T1566, this vulnerability represents a technique for Initial Access through the exploitation of web application vulnerabilities, while the execution phase aligns with T1059 for command and scripting interpreter usage, making it a critical concern for enterprise security posture and compliance requirements.
