CVE-2016-15011: e-Contract dssp SignResponseVerifier.java checkSignResponse xml external entity reference

A vulnerability classified as problematic was found in e-Contract dssp up to 1.3.1. Affected by this vulnerability is the function checkSignResponse of the file dssp-client/src/main/java/be/e_contract/dssp/client/SignResponseVerifier.java. The manipulation leads to xml external entity reference. Upgrading to version 1.3.2 is able to address this issue. The identifier of the patch is ec4238349691ec66dd30b416ec6eaab02d722302. It is recommended to upgrade the affected component. The identifier VDB-217549 was assigned to this vulnerability.

Security readout for executives and security teams

Plain-English summary

CVE-2016-15011 affects e-Contract dssp versions 1.3.0 and 1.3.1. A flawed XML handling path in signature response verification can allow XML external entity behavior, creating limited confidentiality, integrity, and availability risk. The named fix is upgrading to dssp 1.3.2.

Executive priority

Schedule remediation in the normal vulnerability cycle, faster for externally connected or partner-facing DSSP workflows. The issue has a clear upgrade path and moderate technical impact, but no provided evidence of active exploitation.

Technical view

The issue is CWE-611 in checkSignResponse within SignResponseVerifier.java. The source bundle says crafted manipulation can trigger XML external entity reference handling. CVSS 3.1 is 5.5 with adjacent attack vector, low complexity, low privileges, no user interaction, and low CIA impact.

Likely exposure

Exposure is limited to systems that embed or depend on e-Contract dssp 1.3.0 or 1.3.1 and process DSSP SignResponse XML. The bundle does not identify other affected products or deployment patterns.

Exploitation context

The bundle marks KEV as false and provides no cited evidence of active exploitation. VulDB assigns VDB-217549 and the CVSS vector requires adjacent access and low privileges. Treat exploit status as unconfirmed, not actively exploited.

Researcher notes

Evidence is specific but narrow: affected versions, vulnerable file/function, CWE-611, CVSS vector, and patch identifiers are provided. The bundle does not provide exploit details, environmental prerequisites beyond CVSS, or proof of exploitation.

Mitigation direction

  • Upgrade affected e-Contract dssp deployments to version 1.3.2.
  • Confirm the ec423834 patch is included in deployed builds.
  • Review vendor release notes before relying on compensating controls.
  • Prioritize systems that process untrusted or partner-supplied SignResponse XML.

Validation and detection

  • Search SBOMs and dependency manifests for e-Contract dssp versions 1.3.0 or 1.3.1.
  • Verify production artifacts report dssp 1.3.2 after remediation.
  • Review code paths that call checkSignResponse or process DSSP SignResponse XML.
  • Confirm vulnerability scanners map findings to CVE-2016-15011 or VDB-217549.
