A newly discovered vulnerability categorized as CVE-2023-44973 has been found within the /content/templates/ component of Emlog Pro v2.2.. Exploiting this vulnerability potentially allows attackers to upload and execute arbitrary PHP files on the target server, jeopardizing the security and stability of the system. CVE-2023-44973 represents a severe threat to websites running this version of Emlog Pro.

Vulnerability Details

The arbitrary file upload vulnerability specifically affects the /content/templates/ component within Emlog Pro v2.2.. Attackers can exploit this issue by uploading a carefully crafted PHP file with malicious code to the target server, ultimately allowing them to execute the code remotely.

For a clearer understanding, the following code snippet demonstrates a simple PHP payload that an attacker can use to upload and exploit this vulnerability:

<?php
    system($_GET['cmd']);
?>

Upon successful execution, this malicious PHP file (e.g., exploit.php) would allow an attacker to run arbitrary system-level commands on the server by calling the URL, such as:

https://victim.com/content/templates/exploit.php?cmd=whoami

The attacker would now have control over the system and could potentially carry out nefarious activities such as data exfiltration, remote code execution, or installing additional malware.

Exploit Recommendation

Server administrators and website owners are strongly encouraged to update their Emlog Pro software immediately to the latest patched version to protect their websites from potential attacks. In addition, applying strict file upload validation and securing the file upload folder by disabling script executions can further reduce the risks associated with this vulnerability.

For those who cannot immediately update their Emlog Pro to a secure version, a temporary mitigation would be to disable the affected /content/templates/ component or at least block PHP file uploads to the directory. However, this is not a fool-proof solution and updating the software remains highly recommended.

Conclusion

In summary, CVE-2023-44973 is a dangerous vulnerability affecting Emlog Pro v2.2., allowing attackers to upload and execute arbitrary PHP files on the target server remotely. By exploiting this vulnerability, attackers can gain control of the server and perform various malicious actions. As such, it is crucial for Emlog Pro v2.2. users to take immediate steps to secure their server and protect their websites from potential attacks.
