Security readout for executives and security teams
Plain-English summary
This is a medium-severity cross-site scripting issue in Overdrive Eletrônica course-builder versions 1.0 through 1.7. A remote, authenticated attacker may be able to affect page behavior in the oeditor component. The available sources name version 1.8.0 as the fix. There is no cited evidence of active exploitation.
Executive priority
Treat this as a targeted remediation item, not an emergency. Prioritize upgrade where course-builder is internet-facing, used by many authenticated users, or embedded in trusted workflows where XSS could affect content integrity.
Technical view
CVE-2015-10049 is a CWE-79 XSS vulnerability in coursebuilder/modules/oeditor/oeditor.html. The CVSS 2.0 vector is AV:N/AC:L/Au:S/C:N/I:P/A:N, indicating network reachability, low complexity, required authentication, partial integrity impact, and no confidentiality or availability impact. The source bundle does not describe the exact vulnerable parameter or code path.
Likely exposure
Exposure is limited to organizations running Overdrive Eletrônica course-builder 1.0 through 1.7, especially where authenticated users can reach the oeditor module. Products outside course-builder are not identified in the sources.
Exploitation context
The sources state the attack can be launched remotely and requires authentication. KEV status is false, and the provided sources do not claim active exploitation, public weaponization, or observed attacks.
Researcher notes
Public evidence identifies XSS in oeditor.html but does not specify the exact input, trigger, or sink. Validation should stay version- and patch-focused unless vendor details are reviewed. Do not assume unauthenticated exploitability because the CVSS vector requires authentication.
Mitigation direction
- Upgrade Overdrive Eletrônica course-builder to version 1.8.0.
- Verify patch commit e39645fd714adb7e549908780235911ae282b21b is present.
- Limit editor access to trusted authenticated users until upgraded.
- Check vendor repository guidance for any later security notes.
Validation and detection
- Inventory deployed course-builder versions and identify any 1.0 through 1.7 instances.
- Confirm oeditor.html comes from version 1.8.0 or includes the named patch.
- Verify only intended authenticated users can access the editor module.
- Review relevant logs for unusual authenticated editor access if externally reachable.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
