01

What, why and how

Microsoft Windows Task Scheduler contains a privilege escalation vulnerability that can allow an attacker-provided, local application to escalate privileges outside of its AppContainer, and access privileged RPC functions.

What

Microsoft Windows Task Scheduler contains a privilege escalation vulnerability that can allow an attacker-provided, local application to escalate privileges outside of its AppContainer, and access privileged RPC functions.

Why

The affected component does not establish the requesting party's identity reliably before granting access.

How

An attacker operating through local access may attempt exploitation with low privileges. If successful, the issue may gain additional privileges.

What

How

An attacker operating through local access may attempt exploitation with low privileges. If successful, the issue may gain additional privileges.

02

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 2024-11-12. 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
local access → Improper Authentication → gain additional privileges
Attack surface
Local
Privileges required
Low: a basic authenticated account is required
User interaction
None
Attack complexity
Low: no specialised conditions are recorded
Security boundary
Changed: exploitation can affect a different security authority
Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-287 ↗

CWE-287: Improper Authentication. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.

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

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

AVLocalAttack vector: The attacker needs local access to the vulnerable system.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.SChangedScope: The attack can affect a component governed by a different security 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
The issue can support a local privilege or sandbox boundary transition; normal system utilities may then be available in the gained context.

NCSC-NL · Dutch · NCSC-2024-0434Kwetsbaarheden verholpen in Microsoft Windows

Een kwaadwillende kan de kwetsbaarheden misbruiken om aanvallen uit te voeren die kunnen leiden tot de volgende categorieën schade: - Denial-of-Service (DoS) - Uitvoer van willekeurige code (Gebruikersrechten) - Uitvoer van willekeurige code (Systeemrechten) - Verkrijgen van verhoogde rechten - Toegang tot gevoelige gegevens - Spoofing Van de kwetsbaarheden met kenmerk CVE-2024-43451 en CVE-2024-49019 geeft Microsoft aan signalen te hebben dat informatie gedeeld wordt in diverse groepen. Van de kwetsbaarheden met kenmerk CVE-2024-43451 en CVE-2024-49039 geeft Microsoft aan dat deze beperkt en gericht zijn misbruikt. Deze kwetsbaarheden bevinden zich respectievelijk in NTLMv2 en de task scheduler en stellen een kwaadwillende in staat zich voor te doen als een andere gebruiker met mogelijk hogere rechten. Succesvol misbruik is niet eenvoudig en vereist dat de kwaadwillende het slachtoffer misleidt een malafide applicatie te draaien. ``` Windows Task Scheduler:
