This flaw resides in versions 4.8.2.9 prior to 4.8.3.2 of DivvyDrive. Open redirect vulnerabilities can be exploited by attackers to craft malicious links that, when clicked, redirect users to attacker-controlled websites. This can be leveraged in phishing campaigns to steal credentials or deliver malware. Defenders should prioritize patching to the latest version or implementing mitigations to prevent abuse of this vulnerability.

Attack Chain

  1. Attacker crafts a malicious URL containing a parameter designed for redirection.
  2. The crafted URL is disseminated via email, social media, or other channels.
  3. A user clicks on the malicious URL, believing it leads to a legitimate DivvyDrive resource.
  4. DivvyDrive processes the URL and the attacker-controlled parameter value.
  5. Due to the open redirect vulnerability, DivvyDrive redirects the user to a malicious external website.
  6. The malicious website may mimic a legitimate login page to harvest credentials.
  7. Alternatively, the malicious website may host and deliver malware to the user’s system.

Impact

Successful exploitation of this open redirect vulnerability can lead to users being redirected to phishing sites or websites hosting malware. This can result in credential theft, malware infection, and potential compromise of user accounts and systems. The impact is significant as it can affect all users of vulnerable DivvyDrive versions, potentially leading to widespread data breaches or system compromise if attackers successfully harvest credentials.

Recommendation

  • Upgrade DivvyDrive to version 4.8.3.2 or later to patch CVE-2026-6795.
  • Implement input validation and sanitization on URL parameters to prevent parameter injection and open redirects.
  • Monitor web server logs for suspicious URL patterns indicative of open redirect attempts. Deploy the Sigma rule Detect Open Redirect Attempts via HTTP Referer to identify potential exploitation.
  • Educate users about the risks of clicking on suspicious links and encourage them to verify the legitimacy of URLs before clicking.
