CVE-2025-63717 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the SourceCodester Pet Grooming Management Software version 1.0, specifically in the administrative password change functionality located at /pet_grooming/admin/change_pass.php. The vulnerability arises because the application does not implement adequate anti-CSRF mechanisms such as unique tokens embedded in forms or enforcing same-site cookie policies, which are critical defenses against CSRF attacks. Without these protections, an attacker can craft a malicious web page or email that, when visited by an authenticated administrator, automatically submits a request to change the administrator's password without their knowledge or consent. This attack does not require the attacker to have any privileges or the victim to perform any explicit action beyond visiting a malicious link or page. The vulnerability impacts confidentiality and integrity by potentially allowing unauthorized password changes, which could lead to account takeover or lockout scenarios. The CVSS 3.1 base score is 6.5, indicating a medium severity level, with the vector showing network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and impacts on confidentiality and integrity but not availability. No patches or known exploits are currently reported, but the lack of mitigation makes this a credible risk for affected users. The vulnerability is categorized under CWE-352 (Cross-Site Request Forgery).

For European organizations using SourceCodester Pet Grooming Management Software 1.0, this vulnerability poses a risk primarily to administrative account security. Successful exploitation could allow attackers to change administrator passwords without authorization, potentially leading to account lockout or unauthorized access if the attacker can set a password they control. This undermines the confidentiality and integrity of administrative credentials and could disrupt management operations. In sectors such as pet grooming services, where customer data and scheduling information may be stored, unauthorized access could lead to data breaches or service disruption. Although availability is not directly impacted, the loss of administrative control can indirectly affect service continuity. The medium severity rating reflects that exploitation is feasible over the network without privileges or user interaction, increasing the risk profile. European organizations with limited security monitoring or those that have not implemented compensating controls are particularly vulnerable. The absence of known exploits suggests a window for proactive mitigation before widespread attacks occur.

To mitigate this vulnerability, organizations should implement robust anti-CSRF protections immediately. This includes adding unique, unpredictable CSRF tokens to all state-changing forms, especially the password change form, and validating these tokens server-side upon form submission. Additionally, configuring cookies with the SameSite attribute (preferably 'Strict' or 'Lax') will reduce the risk of cross-origin requests being accepted. If possible, upgrading to a newer, patched version of the software or applying vendor-provided patches is recommended once available. In the interim, restricting access to the administrative interface by IP whitelisting or VPN-only access can reduce exposure. Monitoring administrative account activities and implementing multi-factor authentication (MFA) for admin accounts can further limit the impact of compromised credentials. Educating administrators to avoid clicking suspicious links while authenticated can also help reduce risk. Finally, conducting regular security assessments and penetration testing on web applications will help identify similar vulnerabilities proactively.
