DOM-based cross-site scripting in baserCMS tag creation functionality allows remote attackers to execute malicious JavaScript in victim browsers. Affects all baserCMS versions prior to 5.2.3. The vulnerability requires user interaction (CVSS UI:R) but needs no authentication (PR:N), enabling phishing or social engineering attacks. EPSS data not available; no public exploit identified at time of analysis. Vendor-released patch available in version 5.2.3.
Authenticated path traversal in baserCMS theme file management API (versions prior to 5.2.3) enables arbitrary file write, allowing administrators to create malicious PHP files outside the theme directory and achieve remote code execution. The vulnerability (CWE-22) requires high privileges (PR:H) but has low attack complexity (AC:L) with network access (AV:N). CVSS score of 7.2 reflects the significant impact when administrator credentials are compromised. No public exploit code or CISA KEV listing identified at time of analysis, though the technical details in the advisory provide sufficient information for weaponization.
OS command injection in baserCMS update functionality allows authenticated administrators to execute arbitrary commands on the server with application privileges. Affects baserCMS versions prior to 5.2.3. Vendor-released patch available in version 5.2.3. CVSS 9.1 reflects high impact with changed scope, though exploitation requires high-privilege administrator access (PR:H). No public exploit identified at time of analysis. EPSS data not provided, but attack complexity is low (AC:L) once admin credentials are obtained.
OS command injection in baserCMS installer prior to version 5.2.3 allows remote attackers to execute arbitrary system commands during the installation process. The vulnerability exists in the installer component and has been patched in version 5.2.3. Attack complexity appears low given the installer context, though CVSS metrics are unavailable for detailed severity assessment.
OS command injection in baserCMS core update functionality allows authenticated administrators to execute arbitrary system commands on the server. The vulnerability affects baserCMS versions prior to 5.2.3, stemming from improper sanitization of user-controlled input passed directly to exec() functions. With CVSS 9.1 (Critical) due to network accessibility, low complexity, and cross-scope impact, this represents a severe risk in multi-tenant or managed hosting environments where administrative boundaries must be enforced. EPSS data not available, no CISA KEV listing confirmed, and authentication requirements (PR:H) limit exploit surface to compromised or malicious administrator accounts.
Cross-site scripting (XSS) vulnerability in baserCMS prior to version 5.2.3 allows attackers to inject malicious scripts into blog posts, potentially enabling session hijacking, credential theft, or malware distribution to site visitors. The vulnerability affects the blog post functionality and has been patched in version 5.2.3; no public exploit code or active exploitation has been confirmed at time of analysis.
baserCMS versions prior to 5.2.3 allow unauthenticated remote attackers to bypass administrative form submission controls via a public mail API, enabling arbitrary form submissions even when the form is configured to reject new entries. This authentication bypass has a CVSS score of 5.3 and permits attackers to inject spam or abuse content without authorization, circumventing intended intake restrictions. Vendor-released patch available in version 5.2.3.
SQL injection in baserCMS prior to version 5.2.3 allows unauthenticated remote attackers to execute arbitrary SQL queries through unvalidated input in blog post functionality. The vulnerability affects all versions before 5.2.3 and has been patched; no public exploit code or active exploitation has been confirmed at the time of analysis.
Arbitrary code execution in baserCMS versions before 5.2.3 allows authenticated administrators to achieve remote code execution via malicious PHP files embedded in backup restore archives. The vulnerability exploits unsafe file inclusion during ZIP extraction in the restore function, where uploaded PHP files are executed via require_once without filename validation. No public exploit identified at time of analysis, though EPSS score of 0.00043 (0.043%) and CVSS 8.7 indicate moderate theoretical risk mitigated by high privilege requirements (PR:H).
