CVE-2011-2039
HighSummary
Aplikacja pomocnicza w Cisco AnyConnect Secure Mobility Client przed wersją 2.3.185 na systemy Windows oraz Windows Mobile pobiera plik wykonywalny klienta (vpndownloader.exe) bez weryfikacji jego autentyczności. To umożliwia zdalnym atakującym wykonanie dowolnego kodu poprzez właściwość url w określonym kontrolerze ActiveX w vpnweb.ocx.
Risk Assessment
Podatność ta stwarza poważne ryzyko dla organizacji, ponieważ umożliwia zdalne wykonanie kodu, co może prowadzić do przejęcia kontroli nad systemem. Atakujący mogą wykorzystać tę lukę do wprowadzenia złośliwego oprogramowania.
Recommendation
Zaleca się aktualizację Cisco AnyConnect Secure Mobility Client do najnowszej wersji, aby usunąć tę podatność. Dodatkowo, warto wdrożyć mechanizmy weryfikacji autentyczności pobieranych plików.

SunEditor before 3.4.0 contains a stored cross-site scripting vulnerability because the html.clean() sanitizer's _normalizeURL() function decodes named entities like : to an empty string. Attackers can inject href values such as javascript: that pass the _isSafeURL() check but are decoded by browsers, executing JavaScript when victims click stored links.
- CVE-2026-124493Critical
SunEditor before 3.4.0 contains a stored cross-site scripting vulnerability in the DocumentType constructor that injects header textContent into innerHTML without HTML escaping. Attackers can store entity-encoded HTML in h1-h6 headers that executes JavaScript when editors using document:header mode initialize, enabling session cookie theft.

OpenEMR before 8.3.0 contains a path traversal vulnerability in the RingCentral RCFaxClient disposeDocument() method of oe-module-faxsms that allows authenticated attackers to read and write arbitrary files via the file_path parameter. Attackers can use action=download to read credentials and source code, or action=setup with base64 content to write web-executable files for code execution.
Original NVD description (English source)
The helper application in Cisco AnyConnect Secure Mobility Client (formerly AnyConnect VPN Client) before 2.3.185 on Windows, and on Windows Mobile, downloads a client executable file (vpndownloader.exe) without verifying its authenticity, which allows remote attackers to execute arbitrary code via the url property to a certain ActiveX control in vpnweb.ocx, aka Bug ID CSCsy00904.
