The BWOCXRUN.BwocxrunCtrl.1 control contains a method named
“OpenUrlToBuffer.” This method takes a URL as a parameter and returns
its contents to the caller in JavaScript. The URLs are accessed in the
security context of the current browser session. The control does not
perform any URL validation and allows “file://” URLs that access the
local disk.
The method can be used to open a URL (including file URLs) and read
file URLs through JavaScript. This method could also be used to reach
any arbitrary URL to which the browser has access.
CISA SSVCTrack at low or medium mission impact; Track or Track* or Attend at high (mission-essential systems).
No fix is confirmed yet. Restrict network exposure of the affected system or apply the vendor's mitigation within your standard update timelines at low or medium mission impact and sooner than that at high, and watch the vendor's advisory for the fix.
Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact unknown (not published for this CVE). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
