What is CVE-2019-19702?

CVE-2019-19702 is a high-severity security vulnerability in modoboa-dmarc (pip), affecting versions < 1.2.0. It is fixed in 1.2.0.

How severe is CVE-2019-19702?

CVE-2019-19702 has a CVSS score of 7.5 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.

Which versions of modoboa-dmarc are affected by CVE-2019-19702?

modoboa-dmarc (pip) versions < 1.2.0 is affected.

Is there a fix for CVE-2019-19702?

Yes. CVE-2019-19702 is fixed in 1.2.0. Upgrade to this version or later.

Is CVE-2019-19702 exploitable, and should I be worried?

Whether CVE-2019-19702 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

What actually determines whether CVE-2019-19702 is exploitable, and how bad it is?

Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.

Summary

Modoboa is vulnerable to an XML External Entity Injection (XXE)

The modoboa-dmarc plugin 1.1.0 for Modoboa is vulnerable to an XML External Entity Injection (XXE) attack when processing XML data. A remote attacker could exploit this to perform a denial of service against the DMARC reporting functionality, such as by referencing the /dev/random file within XML documents that are emailed to the address in the rua field of the DMARC records of a domain.

Impact

CVE-2019-19702 has a CVSS score of 7.5 (High). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (1.2.0); upgrading removes the vulnerable code path.

Affected versions

modoboa-dmarc (< 1.2.0)

Security releases

modoboa-dmarc → 1.2.0 (pip)

Kodem intelligence

Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.

Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.
