CVE-2013-4170
MEDIUMCVE-2013-4170 is a medium-severity (CVSS 6.1) Cross-site Scripting (XSS) vulnerability in emberjs ember.js. O3 Security detects and blocks CVE-2013-4170 exploitation at runtime via eBPF exploit-chain detection and L7 egress monitoring, even on unpatched systems.

EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
Description
In general, Ember.js escapes or strips any user-supplied content before inserting it in strings that will be sent to innerHTML. However, the tagName property of an Ember.View was inserted into such a string without being sanitized. This means that if an application assigns a view's tagName to user-supplied data, a specially-crafted payload could execute arbitrary JavaScript in the context of the current domain ("XSS"). This vulnerability only affects applications that assign or bind user-provided content to tagName.

Vendor / applianceDetect
Inventory every emberjs ember.js deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for exploitation at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.
Fix
Apply the emberjs ember.js security patch or hotfix for CVE-2013-4170 on the affected version, following the vendor advisory for your exact build.
Workarounds
Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.
How O3 protects you
O3 detects and blocks CVE-2013-4170 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.
Tailored to CVE-2013-4170. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2013-4170 being exploited in your environment?
O3's eBPF runtime sensors and L7 egress monitoring detect and block the CVE-2013-4170 exploit chain at execution — protecting unpatched and end-of-life systems until the vendor patch is applied.
