CVE-2011-0656
HighSummary
W programach Microsoft PowerPoint oraz powiązanych aplikacjach występuje luka związana z niewłaściwą walidacją rekordów PersistDirectoryEntry w dokumentach PowerPoint. Atakujący mogą wykorzystać tę podatność do wykonania dowolnego kodu lub spowodowania awarii usługi poprzez złośliwy slajd z nieprawidłowym rekordem.
Risk Assessment
Podatność ta stwarza ryzyko zdalnego wykonania kodu, co może prowadzić do przejęcia kontroli nad systemem lub utraty danych. Dodatkowo, może powodować awarie usług, co wpływa na dostępność aplikacji.
Recommendation
Zaleca się aktualizację oprogramowania do najnowszych wersji, które zawierają poprawki bezpieczeństwa. Należy również ograniczyć otwieranie dokumentów PowerPoint z nieznanych źródeł.

- CVE-2026-124494Critical
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)
Microsoft PowerPoint 2002 SP3, 2003 SP3, 2007 SP2, and 2010; Office 2004, 2008, and 2011 for Mac; Open XML File Format Converter for Mac; Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats SP2; PowerPoint Viewer; PowerPoint Viewer 2007 SP2; and PowerPoint Web App do not properly validate PersistDirectoryEntry records in PowerPoint documents, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a Slide with a malformed record, which triggers an exception and later use of an unspecified method, aka "Persist Directory RCE Vulnerability."
