CVE-2025-4570 is a vulnerability identified in the ASUS MyASUS application, specifically versions 4.0.35.0 and earlier. The issue is categorized under CWE-798, which pertains to the use of hard-coded credentials. In this case, MyASUS contains an insecure sensitive key storage flaw where a hard-coded token or credential is embedded within the application. This token can potentially be extracted by an unauthorized actor without requiring any privileges or user interaction. Once obtained, the token may allow the attacker to communicate with certain ASUS services, potentially leading to unauthorized access or manipulation of service interactions. The vulnerability has a CVSS 4.0 base score of 6.9, indicating a medium severity level. The vector metrics show that the attack can be performed remotely (AV:N), with low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The impact is limited to confidentiality (VC:L) with no impact on integrity or availability. No known exploits are currently reported in the wild, and no patches have been linked yet, though ASUS has acknowledged the issue in their security advisory. This vulnerability highlights the risks of embedding static credentials in software, which can be extracted and abused by attackers to bypass authentication or gain unauthorized access to backend services.

For European organizations using ASUS laptops or devices with the MyASUS application installed, this vulnerability poses a risk of unauthorized access to ASUS service communications. While the direct impact on enterprise systems may be limited, the exposure of hard-coded tokens could allow attackers to impersonate legitimate devices or users in interactions with ASUS services, potentially leading to data leakage or unauthorized configuration changes. This could indirectly affect device management, warranty services, or software update mechanisms. Given that no user interaction or privileges are required, the attack surface is broad, increasing the likelihood of exploitation if attackers target ASUS device users. Organizations relying on ASUS hardware for critical operations may face confidentiality risks, especially if the token can be leveraged to pivot into internal networks or escalate privileges. However, the absence of known exploits and the medium severity rating suggest the immediate risk is moderate but should not be ignored. The vulnerability also underscores the importance of secure credential management in vendor-supplied software, as weaknesses here can undermine overall device security.

European organizations should take the following specific steps to mitigate this vulnerability: 1) Inventory all ASUS devices running MyASUS version 4.0.35.0 or earlier and prioritize them for remediation. 2) Monitor ASUS security advisories closely for the release of official patches or updates addressing CVE-2025-4570 and apply them promptly once available. 3) Until patches are available, consider disabling or uninstalling the MyASUS application if it is not essential, to reduce exposure. 4) Implement network-level controls to restrict outbound communications from ASUS devices to only trusted ASUS service endpoints, limiting potential misuse of compromised tokens. 5) Employ endpoint detection and response (EDR) solutions to monitor for unusual behaviors or unauthorized communications originating from ASUS devices. 6) Educate IT and security teams about the risks of hard-coded credentials and encourage reporting of suspicious activity related to ASUS device communications. 7) Engage with ASUS support channels to confirm remediation timelines and request guidance on interim protective measures. These targeted actions go beyond generic patching advice by focusing on device inventory, network segmentation, and proactive monitoring specific to the affected product and vulnerability.
