Overview

Attribute Value
CVE ID CVE-2025-48633
Severity Medium
CVSS Score 5.5
Affected Product Android Framework
Vulnerability Type Information Disclosure
CWE CWE-200

Description

Information disclosure vulnerability in Android Framework. Added to CISA KEV catalog based on evidence of active exploitation.

Affected Versions

  • Android OS

Verification Process

The PoC uses a multi-stage verification approach:

Step 1: Product/Version Detection (Passive)

[*] Query target endpoint
[*] Detect product signatures and extract version
[*] Check if version is in vulnerable range

Step 2: Active Vulnerability Testing

Method Description Detection
Error-based Inject payloads that trigger error messages Error indicators in response
Timing-based Inject delay commands and measure response Response time > baseline + delay
Response-based Check for expected patterns in response Pattern match in response body
Callback-based Trigger OOB request to attacker server HTTP request received

Usage

# Full vulnerability check (version + active testing)
python3 poc.py -t https://target.com -c

# Version-only check (passive, no payloads sent)
python3 poc.py -t https://target.com -c --version-only

# With OOB callback (most reliable)
python3 poc.py -t https://target.com -c --callback http://your-server.com

Mitigation

  1. Upgrade to the latest patched version
  2. Apply workarounds if patch unavailable
  3. Monitor for exploitation attempts
  4. Network segmentation to limit exposure
