CVE-2022-45039: n/a in n/a
An arbitrary file upload vulnerability in the Server Settings module of WBCE CMS v1.5.4 allows attackers to execute arbitrary code via a crafted PHP file.
AI Analysis
Technical Summary
CVE-2022-45039 is a high-severity arbitrary file upload vulnerability identified in the Server Settings module of WBCE CMS version 1.5.4. This vulnerability allows an attacker with high privileges (PR:H) to upload crafted PHP files to the server without requiring user interaction (UI:N). The vulnerability arises due to insufficient validation or sanitization of uploaded files, categorized under CWE-434 (Unrestricted Upload of File with Dangerous Type). Exploiting this flaw enables an attacker to execute arbitrary code on the affected system, potentially leading to full system compromise. The CVSS v3.1 base score is 7.2, reflecting the network attack vector (AV:N), low attack complexity (AC:L), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no known exploits have been reported in the wild, the vulnerability poses a significant risk given the ease of exploitation and the critical impact of successful attacks. The Server Settings module is a core administrative component, and exploitation requires authenticated access with high privileges, indicating that attackers must first compromise or have legitimate access to an administrative account. The vulnerability affects WBCE CMS v1.5.4, a content management system used for website management, which may be deployed in various organizational contexts. The lack of vendor or product information beyond WBCE CMS limits the scope of affected systems to this specific CMS and version. No official patches or mitigation links are currently provided, emphasizing the need for immediate attention from administrators using this CMS version.
Potential Impact
For European organizations using WBCE CMS v1.5.4, this vulnerability presents a critical risk. Successful exploitation can lead to arbitrary code execution, enabling attackers to take full control of the web server hosting the CMS. This can result in data breaches compromising sensitive information, defacement or disruption of websites, and use of compromised servers as pivot points for further network intrusion. Organizations in sectors such as government, education, media, and small to medium enterprises that rely on WBCE CMS for their web presence are particularly at risk. The high impact on confidentiality, integrity, and availability means that critical services could be disrupted, damaging organizational reputation and causing regulatory compliance issues under GDPR. Since exploitation requires high privilege authentication, the threat is heightened if credential theft or insider threats are present. The absence of known exploits in the wild may reduce immediate risk, but the vulnerability's characteristics make it a likely target for attackers seeking to leverage web server access for broader attacks.
Mitigation Recommendations
1. Immediate mitigation should focus on restricting access to the Server Settings module to only trusted administrators and enforcing strong authentication mechanisms, including multi-factor authentication, to reduce the risk of credential compromise. 2. Conduct a thorough audit of user privileges to ensure that only necessary personnel have high-level access. 3. Implement strict file upload validation controls at the web server and application level, including whitelisting allowed file types and scanning uploaded files for malicious content. 4. If possible, disable or restrict file upload functionality in the Server Settings module until a vendor patch is available. 5. Monitor web server logs and application logs for suspicious upload attempts or execution of unexpected PHP files. 6. Employ web application firewalls (WAFs) with custom rules to detect and block attempts to upload or execute unauthorized PHP files. 7. Regularly back up website data and configurations to enable rapid recovery in case of compromise. 8. Engage with the WBCE CMS community or vendor channels to obtain updates or patches addressing this vulnerability. 9. Consider isolating the CMS environment in a segmented network zone to limit lateral movement if exploitation occurs.
