CVE-2024-49070: Microsoft SharePoint Remote Code Execution Vulnerability

Noroxi assessment

Priority: Monitor (action score 30/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 2.2% (FIRST EPSS); higher than 82.9% of all records.
  • Someone with local access to the system can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: Microsoft SharePoint Enterprise Server 2016 16.0.5478.1000; Microsoft SharePoint Server 2019 16.0.10416.20026; Microsoft SharePoint Server Subscription Edition 16.0.17928.20290.

Low priority for now. Upgrade to Microsoft SharePoint Enterprise Server 2016 16.0.5478.1000; Microsoft SharePoint Server 2019 16.0.10416.20026; Microsoft SharePoint Server Subscription Edition 16.0.17928.20290 or later.

Weakness class (CWE)

CWE-502 · Deserialization of Untrusted Data

CVSS vector

CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H

nvd-secondary

Root cause

Data received over the network is deserialized into the language’s native object format without verifying its source. Code paths inside the object can be triggered during deserialization.

The bug in code

The whole CWE-502 class

A representative example of this vulnerability class. Not the vendor's source code; it shows the faulty pattern and its fix.

Vulnerable

python
payload = sock.recv(65536)job = pickle.loads(payload)

Fixed

python
payload = sock.recv(65536)if not hmac.compare_digest(sign(payload), header_sig):    raise PermissionError("invalid signature")job = JobSchema.validate(json.loads(payload))
