Halo Surface Signal score for CVE-2023-3632

The vulnerability is a hard-coded cryptographic key within the client-side Kunduz Homework Helper mobile application. As the vulnerability resides in a client-side mobile application binary, the vulnerable attack surface is client-side rather than a public-facing network-accessible service or server.

Horizon Alert

Summary of the vulnerability and why it matters

This vulnerability in the Kunduz Homework Helper App involves a hard-coded cryptographic key, allowing unauthorized access and bypass of authentication. This could significantly compromise user data and application integrity.

  • Affects user accounts.
  • Enables unauthorized access.
  • Impacts data confidentiality and integrity.

Attack Path

How an attacker could exploit the issue

Attackers can abuse a hard-coded cryptographic key in the Kunduz Homework Helper app to bypass authentication and gain unauthorized access. This allows them to impersonate legitimate users, potentially accessing sensitive data or functionalities intended only for authenticated individuals. The vulnerability is exploitable without prior access or user interaction.

  • Hard-coded key in app.
  • No user interaction needed.
  • Bypasses authentication.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability in the Kunduz Homework Helper app, stemming from a hard-coded cryptographic key, could enable authentication abuse and bypass. Attackers might find it appealing due to the potential for broad impact if the app has a large user base and the difficulty in patching client-side applications. However, the attack surface being client-side limits direct exploitation without user interaction.

  • Vulnerability is client-side.
  • No immediate public exploit observed.
  • App has limited user interaction required.

Priority actions

Operational Fix

Recommended remediation, mitigation, and detection steps

Prioritize patching the Kunduz Homework Helper app to version 6.2.3 or later to address the hard-coded cryptographic key vulnerability. If immediate patching is not feasible, investigate the scope of its use and consider restricting network access for unpatched mobile devices to mitigate the risk of authentication bypass and abuse.

  • Update Kunduz Homework Helper app.
  • Block unpatched app network access.
  • Monitor for auth abuse.

Frequently asked questions
