CVE-2008-6752 in ReVou
Summary
by MITRE
adminlogin/password.php in the Twitter Clone (TClone) plugin for ReVou Micro Blogging does not verify the original password before changing passwords, which allows remote attackers to change the administrator s password and gain privileges via a direct request with modified newpass1 and newpass2 parameters in a Change operation.

The vulnerability identified as CVE-2008-6752 affects the Twitter Clone plugin for ReVou Micro Blogging, specifically targeting the adminlogin/password.php component. This flaw represents a critical authentication bypass vulnerability that fundamentally undermines the security model of the affected system. The vulnerability stems from inadequate input validation and authentication checks within the password change functionality, creating a pathway for unauthorized privilege escalation through simple parameter manipulation.
The technical implementation flaw resides in the password change mechanism where the system fails to validate the existing password before accepting new password parameters. Attackers can exploit this by directly submitting a request to the adminlogin/password.php endpoint with modified newpass1 and newpass2 parameters, effectively bypassing the standard authentication requirements. This vulnerability is classified as a CWE-305 authentication bypass weakness, specifically related to improper authentication checks during password modification operations. The flaw operates at the application layer and can be exploited remotely without requiring prior authentication credentials, making it particularly dangerous for administrative accounts.
The operational impact of this vulnerability extends beyond simple privilege escalation to encompass full administrative control over the affected system. An attacker who successfully exploits this vulnerability can assume complete administrative privileges, potentially leading to data breaches, system compromise, and unauthorized modifications to the microblogging platform. The vulnerability affects the confidentiality, integrity, and availability of the system, as attackers can modify user accounts, access sensitive data, and potentially establish persistent access. This represents a significant risk to the platform's security posture and could enable attackers to leverage the compromised administrative account for further attacks within the network infrastructure.
Mitigation strategies for this vulnerability should include immediate implementation of proper authentication checks before password modifications, ensuring that the current password is verified before accepting new password parameters. The system should enforce strict input validation and implement proper session management to prevent unauthorized access to administrative functions. Security measures should also include rate limiting on authentication attempts and logging of all password change operations for monitoring purposes. Organizations should consider implementing the principle of least privilege, ensuring that administrative functions require additional verification mechanisms beyond simple parameter manipulation. This vulnerability aligns with ATT&CK technique T1078 for valid accounts and T1566 for credential access, highlighting the need for comprehensive security controls that address both authentication and access control mechanisms. Regular security assessments and code reviews should be implemented to identify similar vulnerabilities in other components of the system.
