Published severityHighOperational priority:Critical, raised one band.upgradedsince 22 Jul 2025

Evidence used

  • CISA confirms exploitation in the wild.
  • EPSS is 100.00% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict the affected network interface to trusted sources where business-safe.
  • Increase monitoring for the attack path and post-exploitation behaviour described in the report.

Verification

  1. Confirm that the asset runs Microsoft SharePoint and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: Within 3 daysRemediation target: Within 90 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

01

What, why and how

Microsoft SharePoint contains a code injection vulnerability that could allow an authorized attacker to execute code over a network. This vulnerability could be chained with CVE-2025-49706. CVE-2025-53770 is a patch bypass for CVE-2025-49704, and the updates for CVE-2025-53770 include more robust protection than those for CVE-2025-49704.

CVE-2025-53770 is a patch bypass for CVE-2025-49704, and the updates for CVE-2025-53770 include more robust protection than those for CVE-2025-49704.

Why

Untrusted data can cross into a code-evaluation path and be interpreted as executable instructions.

How

An attacker operating through a network path may attempt exploitation with low privileges. If successful, the issue may execute code or commands in the affected security context.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
Confirmed in the wild

CISA added this CVE to its Known Exploited Vulnerabilities catalogue on 2025-07-22. Known ransomware campaign use is recorded.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
a network path → Improper Control of Generation of Code ('Code Injection') → execute code or commands in the affected security context
Attack surface

Privileges required
Low: a basic authenticated account is required

Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-94 ↗

CWE-94: Improper Control of Generation of Code ('Code Injection'). The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.

CVSS vector
?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C

Common Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.

AVNetworkAttack vector: The vulnerable component can be reached over a network.ACLowAttack complexity: No specialised conditions are required beyond attacker-controlled input.PRLowPrivileges required: The attacker needs basic user-level privileges.UINoneUser interaction: No action by another user is required.SUnchangedScope: The security impact remains within the vulnerable component's authority.CHighConfidentiality impact: A successful attack can cause a major loss.IHighIntegrity impact: A successful attack can cause a major loss.AHighAvailability impact: A successful attack can cause a major loss.
Post-exploitation / living off the land
After compromise, an attacker may use built-in shells, scripting engines, scheduled tasks and native network utilities for discovery, persistence or movement. This is a plausible LoTL path, not evidence that it has occurred for every attack.

Een kwaadwillende kan de kwetsbaarheden misbruiken om zich verhoogde rechten toe te kennen, willekeurige code uit te voeren of toegang krijgen tot gevoelige gegevens. Voor succesvol misbruik moet de kwaadwillende het slachtoffer misleiden een malafide bestand te openen of link te volgen. **UPDATE**: Het NCSC ontvangt meldingen dat de kwetsbaarheden met kenmerk CVE-2025-49704 en CVE-2025-49706 actief worden misbruikt. Deze kwetsbaarheden stellen een kwaadwillende in staat om zich voor te doen als andere gebruiker en willekeurige code uit te voeren, mogelijk met verhoogde rechten. Er is (nog) geen publieke exploitcode bekend en misbruik vindt plaats op publiek toegankelijke sharepoint-installaties. Doordat de kwetsbaarheid de aandacht heeft van onderzoekers en de (toen nog theoretische) mogelijkheid van misbruik is gedemonstreerd tijdens Pwn2Own 2025 Berlijn, verwacht het NCSC een significante toename in pogingen tot misbruik. Voor succesvol misbruik moet de kwaadwillende het slachtoffer misleiden een malafide link te volgen, waarna de kwaadwillende onder de rechten van het slachtoffer code kan uitvoeren. ``` Microsoft Teams: |----------------|------|-------------------------------------| | CVE-ID | CVSS | Impact | |----------------|------|-------------------------------------| | CVE-2025-49731 | 3.10 | Verkrijgen van verhoogde rechten | | CVE-2025-49737 | 7.00 | Verkrijgen van verhoogde rechten | |----------------|------|-------------------------------------| Microsoft Office: |----------------|------|-------------------------------------| | CVE-ID | CVSS | Impact | |----------------|------|-------------------------------------| | CVE-2025-47994 | 7.80 | Verkrijgen van verhoogde rechten | | CVE-2025-49695 | 8.40 | Uitvoeren van willekeurige code | | CVE-2025-49696 | 8.40 | Uitvoeren van willekeurige code | | CVE-2025-49697 | 8.40 | Uitvoeren van willekeurige code | | CVE-2025-49699 | 7.00 | Uitvoeren van willekeurige code | | CVE-2025-49702 | 7.80 | Uitvoeren van willekeurige code | |----------------|------|-------------------------------------| Microsoft Office Word: |----------------|------|-------------------------------------| | CVE-ID | CVSS | Impact | |----------------|------|-------------------------------------| | CVE-2025-49698 | 7.80 | Uitvoeren van willekeurige code | | CVE-2025-49700 | 7.80 | Uitvoeren van willekeurige code | | CVE-2025-49703 | 7.80 | Uitvoeren van willekeurige code | |----------------|------|-------------------------------------| Microsoft Office PowerPoint: |----------------|------|-------------------------------------| | CVE-ID | CVSS | Impact | |----------------|------|-------------------------------------| | CVE-2025-49705 | 7.80 | Uitvoeren van willekeurige code | |----------------|------|-------------------------------------| Microsoft Office SharePoint: |----------------|------|-------------------------------------| | CVE-ID | CVSS | Impact | |----------------|------|-------------------------------------| | CVE-2025-49701 | 8.80 | Uitvoeren van willekeurige code | | CVE-2025-49704 | 8.80 | Uitvoeren van willekeurige code | | CVE-2025-49706 | 6.30 | Voordoen als andere gebruiker | |----------------|------|-------------------------------------| Microsoft Office Excel: |----------------|------|-------------------------------------| | CVE-ID | CVSS | Impact | |----------------|------|-------------------------------------| | CVE-2025-48812 | 5.50 | Toegang tot gevoelige gegevens | | CVE-2025-49711 | 7.80 | Uitvoeren van willekeurige code | |----------------|------|-------------------------------------| ```
