CVE-2025-8815 is a path traversal vulnerability identified in the 猫宁i Morning product, specifically affecting an unknown function within the /index file of the Shiro Configuration component. The vulnerability allows an unauthenticated remote attacker to manipulate input parameters to traverse directories on the server's filesystem. This can lead to unauthorized access to sensitive files outside the intended web root directory. The product uses a rolling release model, which complicates pinpointing exact affected or patched versions. The CVSS 4.0 score is 6.9 (medium severity), reflecting that the attack vector is network-based, requires no privileges or user interaction, and can impact confidentiality, integrity, and availability to a limited extent. The vulnerability does not require authentication and can be exploited remotely, increasing its risk profile. Although no known exploits are currently reported in the wild, public disclosure of the exploit code increases the likelihood of exploitation attempts. The Shiro Configuration component is critical as it typically manages security policies and authentication, so exploitation could lead to exposure of configuration files or other sensitive data, potentially enabling further attacks or system compromise.

For European organizations using 猫宁i Morning, this vulnerability poses a risk of unauthorized disclosure of sensitive configuration files or other critical data stored on affected servers. This could lead to leakage of credentials, internal network information, or other confidential data, undermining the confidentiality and integrity of systems. If attackers gain access to configuration files, they might escalate privileges or pivot within the network, increasing the risk of broader compromise. The remote and unauthenticated nature of the vulnerability means attackers can exploit it without prior access, raising the threat level. Organizations in sectors with strict data protection regulations such as GDPR may face compliance risks and potential fines if sensitive personal data is exposed. Additionally, disruption or manipulation of configuration files could impact service availability or reliability. Given the rolling release model and lack of clear patch information, organizations may find it challenging to verify if their deployments are secure, increasing exposure duration.

European organizations should immediately conduct a thorough audit of their 猫宁i Morning deployments to identify if the affected Shiro Configuration component is in use. Since no official patches or version details are available due to the rolling release model, organizations should: 1) Implement strict input validation and sanitization on all parameters that interact with file paths to prevent traversal sequences such as '../'. 2) Employ web application firewalls (WAFs) with custom rules to detect and block path traversal attack patterns targeting the /index endpoint. 3) Restrict file system permissions to limit the web server's access to only necessary directories, minimizing potential damage from traversal. 4) Monitor logs for suspicious access patterns indicative of path traversal attempts. 5) Engage with the vendor for timely updates or patches and track their release channels closely. 6) Consider isolating the affected service in a segmented network zone to reduce lateral movement risk. 7) If possible, deploy runtime application self-protection (RASP) solutions to detect and block exploitation attempts in real time. These measures go beyond generic advice by focusing on compensating controls and proactive detection in the absence of immediate patches.
