CVE-2010-4686
HighSummary
CallManager Express (CME) w Cisco IOS przed wersją 15.0(1)XA1 nieprawidłowo obsługuje ruch SIP TRUNK, który zawiera skoki prędkości i 'dziwny' rozmiar żądania. To umożliwia zdalnym atakującym spowodowanie odmowy usługi (zużycie pamięci) poprzez wysyłanie tego ruchu przez dłuższy czas.
Risk Assessment
Organizacja może doświadczyć przerwy w dostępności usług związanych z CallManager Express, co może prowadzić do zakłóceń w komunikacji i utraty danych.
Recommendation
Zaleca się aktualizację Cisco IOS do wersji 15.0(1)XA1 lub nowszej, aby zabezpieczyć się przed tą podatnością.

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)
CallManager Express (CME) on Cisco IOS before 15.0(1)XA1 does not properly handle SIP TRUNK traffic that contains rate bursts and a "peculiar" request size, which allows remote attackers to cause a denial of service (memory consumption) by sending this traffic over a long duration, aka Bug ID CSCtb47950.
