CVE-2025-48445 is a high-severity vulnerability identified in the Drupal Commerce Eurobank (Redirect) module, specifically affecting versions prior to 2.1.1. The vulnerability is classified under CWE-863, which pertains to Incorrect Authorization. This means that the module fails to properly enforce authorization checks, allowing unauthorized users to misuse functionality that should be restricted. The vulnerability enables attackers to perform actions that require higher privileges, potentially leading to unauthorized access or manipulation of sensitive operations within the Drupal Commerce Eurobank module. The CVSS v3.1 score of 8.8 reflects a high impact, with the vector indicating that the attack can be performed remotely (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R). The scope is unchanged (S:U), but the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). Although no known exploits are currently reported in the wild, the vulnerability's nature suggests that attackers could exploit it to redirect users or misuse commerce-related functions, potentially leading to data breaches, financial fraud, or service disruption. The lack of available patches at the time of publication increases the urgency for organizations to implement compensating controls and monitor for suspicious activity related to this module.

For European organizations using Drupal Commerce Eurobank, this vulnerability poses significant risks. Given the high impact on confidentiality, integrity, and availability, exploitation could lead to unauthorized financial transactions, exposure of sensitive customer data, and disruption of e-commerce services. Such incidents could result in regulatory penalties under GDPR due to data breaches, financial losses, and reputational damage. The requirement for user interaction means phishing or social engineering could be leveraged to trigger the exploit, increasing the attack surface. Organizations in sectors like banking, retail, and e-commerce that rely on Drupal Commerce Eurobank are particularly at risk. The vulnerability could also be exploited to redirect users to malicious sites, facilitating further attacks such as credential theft or malware distribution. The absence of known exploits currently provides a window for proactive mitigation, but the high CVSS score indicates that once exploit code becomes available, attacks could be severe and widespread.

1. Immediate upgrade to Drupal Commerce Eurobank version 2.1.1 or later once available to ensure the vulnerability is patched. 2. Until patches are released, restrict access to the Commerce Eurobank (Redirect) module functionality to trusted users only, using strict access control lists and role-based permissions. 3. Implement web application firewall (WAF) rules to detect and block suspicious requests targeting the vulnerable module endpoints, especially those attempting unauthorized redirects or unusual parameter manipulation. 4. Conduct thorough logging and monitoring of user activities related to the module, focusing on redirect actions and privilege escalations, to detect potential exploitation attempts early. 5. Educate users about phishing and social engineering risks, as user interaction is required for exploitation, to reduce the likelihood of successful attacks. 6. Perform regular security assessments and penetration testing on Drupal Commerce installations to identify and remediate authorization weaknesses. 7. Isolate critical e-commerce infrastructure from public networks where feasible and employ network segmentation to limit lateral movement in case of compromise.
