Vulnerability from csaf_ncscnl - Published: 2026-01-13 19:18 - Updated: 2026-03-20 14:03Summary
Kwetsbaarheden verholpen in Microsoft Office
Notes
The Netherlands Cyber Security Center (henceforth: NCSC-NL) maintains this page to enhance access to its information and security advisories. The use of this security advisory is subject to the following terms and conditions:
NCSC-NL makes every reasonable effort to ensure that the content of this page is kept up to date, and that it is accurate and complete. Nevertheless, NCSC-NL cannot entirely rule out the possibility of errors, and therefore cannot give any warranty in respect of its completeness, accuracy or continuous keeping up-to-date. The information contained in this security advisory is intended solely for the purpose of providing general information to professional users. No rights can be derived from the information provided therein.
NCSC-NL and the Kingdom of the Netherlands assume no legal liability or responsibility for any damage resulting from either the use or inability of use of this security advisory. This includes damage resulting from the inaccuracy of incompleteness of the information contained in the advisory.
This security advisory is subject to Dutch law. All disputes related to or arising from the use of this advisory will be submitted to the competent court in The Hague. This choice of means also applies to the court in summary proceedings.
Feiten: Microsoft heeft kwetsbaarheden verholpen in diverse Office-producten.
Interpretaties: Een kwaadwillende kan de kwetsbaarheden misbruiken om zich voor te doen als andere gebruiker, toegang te krijgen tot gevoelige gegevens of willekeurige code uit te voeren in de context van het slachtoffer.
Voor succesvol misbruik moet de kwaadwillende geauthenticeerd zijn op het kwetsbare systeem, of het slachtoffer misleiden een malafide bestand te openen of link te volgen.
Van de kwetsbaarheid met kenmerk CVE-2026-20963 wordt gemeld dat deze actief en gericht is misbruikt. De kwetsbaarheid stelt een kwaadwillende in staat om willekeurige code uit te voeren op een kwetsbaar Sharepoint systeem. Met name publiek toegankelijke installaties lopen verhoogd risico op misbruik.
Buiten meldingen van actief misbruik is (nog) geen publieke Proof-of-Concept-code of exploit bekend. Door de media-aandacht echter, verwacht het NCSC dat deze wellicht op korte termijn beschikbaar komt, waardoor het risico op grootschalig misbruik zal toenemen.

CWE-822: Untrusted Pointer Dereference
CWE-918: Server-Side Request Forgery (SSRF)
An untrusted search path vulnerability in Microsoft Office allows an attacker to execute unauthorized local code by exploiting the way Office handles file paths.
CWE-426 - Untrusted Search PathAn SQL injection vulnerability in Microsoft Office SharePoint allows authorized users to remotely execute code over a network, posing a significant security risk.
CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')Improper input validation in Microsoft Office SharePoint allows attackers to execute unauthorized local code, posing a significant security risk.
Improper input neutralization in Microsoft Office SharePoint results in cross-site scripting vulnerabilities that allow authorized attackers to perform network spoofing.
CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')Microsoft Office SharePoint contains a deserialization vulnerability that allows unauthorized remote code execution by processing untrusted data.
9.8 (Critical)
An untrusted pointer dereference vulnerability in Microsoft Office Word allows unauthorized local code execution, posing a significant security risk.
CWE-822 - Untrusted Pointer DereferenceA server-side request forgery (SSRF) vulnerability in Microsoft Office SharePoint allows an authorized attacker to disclose sensitive information over a network.
CWE-918 - Server-Side Request Forgery (SSRF)A use-after-free vulnerability in Microsoft Office allows unauthorized local code execution, posing a significant security risk.
CWE-416 - Use After FreeA use-after-free vulnerability in Microsoft Office allows unauthorized local code execution, posing a significant security risk.
CWE-416 - Use After FreeAn out-of-bounds read vulnerability in Microsoft Office Word allows an unauthorized attacker to execute code locally, posing a significant security risk.
CWE-125 - Out-of-bounds ReadAn out-of-bounds read vulnerability in Microsoft Office Excel allows an unauthorized attacker to execute code locally, posing a significant security risk.
CWE-125 - Out-of-bounds ReadAn untrusted pointer dereference vulnerability in Microsoft Office Excel allows an attacker to execute unauthorized local code by exploiting improper memory handling.
CWE-822 - Untrusted Pointer DereferenceAn untrusted pointer dereference vulnerability in Microsoft Office Excel allows an attacker to execute unauthorized local code by exploiting improper memory handling.
CWE-822 - Untrusted Pointer DereferenceAn improper access control vulnerability in Microsoft Office Excel allows a local unauthorized attacker to bypass a security feature, potentially compromising application security.
A vulnerability in Microsoft Office Excel, termed 'use after free,' allows unauthorized attackers to execute code locally on affected systems.
CWE-416 - Use After FreeAn integer underflow vulnerability in Microsoft Office Excel allows unauthorized attackers to execute code locally.
