CVE-2026-25858 is a critical authentication vulnerability found in macrozheng mall version 1.0.3 and prior. This vulnerability allows an unauthenticated attacker to reset arbitrary user account passwords simply by knowing a victim’s telephone number. The flaw resides in the password reset workflow of the mall-portal, where the password reset process exposes a one-time password (OTP) directly in the API response. It validates password reset requests solely by comparing the provided OTP to a stored value linked to the telephone number, neglecting to verify user identity or ownership of the telephone number.
The severity of this vulnerability is underscored by its CVSS base score of 9.3, categorized as critical due to the high confidentiality and integrity impacts. Attackers may leverage this vulnerability to perform remote account takeover on any user with a known or guessable telephone number. The urgency for organizations is high, as immediate remediation is crucial to prevent unauthorized access to user accounts.
Currently, there is no public proof-of-concept or known exploit available for this vulnerability, but its potential for exploitation remains a significant concern. Organizations using affected versions should prioritize patching to mitigate risks associated with this flaw.
Organizations should act promptly to address this vulnerability in their systems, particularly if they are running macrozheng mall version 1.0.3 or earlier.
Vulnerability Details
The vulnerability allows unauthenticated attackers to reset user passwords through a flawed password reset workflow. The official CVE description states: "macrozheng mall version 1.0.3 and prior contains an authentication vulnerability in the mall-portal password reset workflow that allows an unauthenticated attacker to reset arbitrary user account passwords using only a victim’s telephone number." This vulnerability is classified under CWE-640, indicating a failure to implement proper credential management.
The CVSS score of 9.3 reflects a critical severity classification, indicating a high level of risk associated with this vulnerability. The attack vector is classified as network-based, with low complexity, meaning that an attacker does not require advanced skills to exploit this vulnerability. The lack of required privileges and user interaction further increases the risk.
Technical Analysis
The root cause of this vulnerability lies in improper validation of the password reset process. The system exposes the OTP in the API response and does not verify the identity of the user requesting the password reset. This oversight allows attackers to manipulate the password reset process without any legitimate authority.
The attack vector for this vulnerability is network-based, making it accessible from anywhere without physical proximity to the target. The attack complexity is low, as it does not require advanced techniques or skills. Moreover, no privileges are required to exploit this vulnerability, and user interaction is not needed.
The potential impact of this vulnerability includes significant confidentiality and integrity breaches, as attackers can take over user accounts and access sensitive information. The availability impact is none, but the ramifications of unauthorized access to user accounts can lead to further exploitation and data breaches.
Risk & Impact Analysis
The real-world risk associated with CVE-2026-25858 is substantial, as it allows for remote account takeovers without sophisticated techniques. Organizations utilizing macrozheng mall must recognize the potential blast radius of such an attack, as it can lead to unauthorized access to sensitive user data and further exploitation of the application.
The urgency for organizations to address this vulnerability is critical, given its CVSS score of 9.3 and the nature of the flaw, which enables attackers to easily compromise user accounts. Organizations should prioritize remediation efforts to mitigate this risk and protect user data.
