CVE-2025-43930: Hashview 0.8.1 Account Takeover Vulnerability via Password Reset
Hashview, a popular password recovery tool, is vulnerable to a critical account takeover flaw. This vulnerability, identified as CVE-2025-43930, stems from improper configuration of the SERVER_NAME setting. This can allow attackers to reset passwords and gain control of user accounts.
Vulnerability Details
- CVE ID: CVE-2025-43930
- Description: Hashview 0.8.1 allows account takeover via the password reset feature because
SERVER_NAMEis not configured and thus a reset depends on the Host HTTP header. An attacker can manipulate the Host header during the password reset process to gain unauthorized access. - CVSS Score: 9.8 (Critical)
- CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
- CVSS Explanation: A CVSS score of 9.8 indicates a critical severity. AV:N (Network) means the vulnerability can be exploited over the network. AC:L (Low) indicates that the attack is easily executable. PR:N (None) means no privileges are required. UI:N (None) means no user interaction is required. S:U (Unchanged) means the vulnerability does not affect components beyond its security scope. C:H/I:H/A:H (High Confidentiality, Integrity, and Availability impact) indicates that a successful exploit could lead to complete compromise of the application and its data.
- Exploit Requirements: The attacker needs to send a password reset request and intercept/modify the HTTP Host header.
- Affected Vendor: Hashview
- Affected Product: Hashview
- Affected Version: 0.8.1
- CWE: CWE-472 (External Control of Critical or Sensitive Data)
- CWE Explanation: CWE-472 refers to a vulnerability where an application uses externally-influenced input to control critical data, leading to potentially unauthorized actions or information disclosure. In this case, the HTTP Host header is used to influence the password reset link.

Exploitability & Real-World Risk
This vulnerability is highly exploitable because it doesn't require any special skills or user interaction. An attacker can simply modify the HTTP Host header during a password reset request. In a real-world scenario, an attacker could target Hashview users and gain complete control of their accounts, potentially accessing sensitive data or performing malicious actions on their behalf. This is especially dangerous if Hashview is used in environments where users store valuable credentials or sensitive data.
Recommendations
- Configure SERVER_NAME: Properly configure the
SERVER_NAMEsetting in your Hashview deployment. This will ensure that the application uses the correct hostname for password reset links. - Apply Patches: Check for any available patches or updates from the Hashview developers and apply them immediately.
- Implement Input Validation: Implement robust input validation to prevent manipulation of the Host header or other sensitive data.
- Monitor Network Traffic: Monitor network traffic for suspicious activity, such as unexpected Host header values in password reset requests.
Technical Insight
The vulnerability lies in how Hashview generates password reset links. Without a properly configured SERVER_NAME, the application relies on the HTTP Host header to determine the base URL for the reset link. An attacker can manipulate this header to inject a malicious URL, which, when clicked by the user, redirects them to a fake login page or exposes their reset token.
