A security vulnerability has been detected in Uasoft badaso up to 2.9.7. Affected is the function forgetPassword of the file src/Controllers/BadasoAuthController.php of the component Token Handler. Such manipulation leads to weak password recovery. The attack can be executed remotely. This attack is characterized by high complexity. The exploitability is told to be difficult. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
Uasoft Badaso versions up to 2.9.7 are vulnerable to a weak password recovery attack due to a flaw in the forgetPassword function. This allows attackers to potentially compromise user accounts remotely, posing a significant risk of unauthorized access and data breaches. The vendor has not responded to the disclosure, increasing the urgency of patching.
Step 1: Request Password Reset: The attacker initiates a password reset request via the forgetPassword function, typically by providing a valid email address associated with a Badaso user account.
Step 2: Token Generation: The vulnerable application generates a password reset token. The weakness lies in the token generation process, which might be predictable or easily guessable.
Step 3: Token Interception/Guessing: The attacker attempts to obtain or guess the password reset token. This could involve intercepting the email containing the token, brute-forcing the token, or exploiting weaknesses in the token generation algorithm.
Step 4: Password Reset: The attacker uses the obtained token to reset the victim's password, gaining unauthorized access to the account.
The vulnerability lies within the forgetPassword function of src/Controllers/BadasoAuthController.php. The root cause is likely a flawed implementation of the password reset mechanism. Specifically, the system probably uses a predictable or easily guessable token generation method for password reset links. This could involve using a weak random number generator, predictable timestamps, or other easily manipulated parameters in the token generation process. Furthermore, the system may not adequately validate the token's authenticity or enforce rate limiting on password reset requests, allowing attackers to brute-force or enumerate valid tokens. The lack of vendor response suggests a potential lack of security awareness or resources to address the issue, compounding the risk.
While no specific APTs are directly linked at this time, the public disclosure and ease of exploitation could attract a wide range of attackers, including script kiddies and opportunistic cybercriminals. The lack of vendor response is a significant red flag. CISA KEV status is likely to be assigned soon if not already.
Monitor web server logs for suspicious activity related to password reset requests, such as a high volume of requests from a single IP address or unusual patterns in request parameters.
Analyze network traffic for requests to the forgetPassword endpoint, looking for unusual payloads or repeated attempts.
Implement intrusion detection system (IDS) rules to identify attempts to exploit the vulnerability, such as those targeting the password reset token generation or validation process.
Monitor email logs for password reset emails, looking for unusual patterns or suspicious recipients.
Immediately update to a patched version of Uasoft Badaso (if available).
Implement strong password reset token generation using cryptographically secure random number generators (CSPRNGs).
Enforce rate limiting on password reset requests to mitigate brute-force attacks.
Implement robust token validation, including checking the token's expiration time and ensuring it is associated with the correct user.
Consider implementing multi-factor authentication (MFA) to further secure user accounts.
Review and harden the application's security configuration, including input validation and output encoding to prevent other potential vulnerabilities.
If no patch is available, consider disabling the password reset functionality until a fix is available. Alternatively, implement a temporary workaround, such as requiring manual password resets by an administrator.
