CVE-2010-4679
HighSummary
Urządzenia Cisco Adaptive Security Appliances (ASA) serii 5500 z oprogramowaniem przed wersją 8.2(3) nieprawidłowo obsługują błędy połączeń protokołu OCSP, co pozwala zdalnym responderom OCSP na wywołanie odmowy usługi poprzez odrzucenie prób połączenia.
Risk Assessment
Atakujący może wykorzystać tę podatność do wyczerpania gniazd TCP, co prowadzi do niedostępności usług dla użytkowników. Może to wpłynąć na ciągłość działania organizacji i jej zdolność do obsługi ruchu sieciowego.
Recommendation
Zaleca się aktualizację oprogramowania urządzeń ASA do wersji 8.2(3) lub nowszej, aby usunąć tę podatność i poprawić obsługę błędów OCSP.

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)
Cisco Adaptive Security Appliances (ASA) 5500 series devices with software before 8.2(3) do not properly handle Online Certificate Status Protocol (OCSP) connection failures, which allows remote OCSP responders to cause a denial of service (TCP socket exhaustion) by rejecting connection attempts, aka Bug ID CSCsz36816.
