Description

A vulnerability has been found in mwasikz robo-cafe-rms up to 228c44a02823f04e85db32b7137809a2856148fc. The affected element is an unknown function of the file manage-food.php. Such manipulation leads to unrestricted upload. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. This product operates on a rolling release basis, ensuring continuous delivery. Consequently, there are no version details for either affected or updated releases. The vendor was contacted early about this disclosure but did not respond in any way.

  "executiveSummary": "A critical security vulnerability has been identified in the mwasikz robo-cafe-rms repository, affecting all versions up to commit 228c44a02823f04e85db32b7137809a2856148fc. The vulnerability is classified as an Unrestricted Upload of File with Dangerous Type.\nThe flaw resides within the manage-food.php file, where the application fails to adequately sanitize or validate file inputs during the upload process. This allows remote, unauthenticated attackers to upload arbitrary files, including executable server-side scripts such as PHP shells, directly onto the web server.\nSuccessful exploitation of this vulnerability enables remote code execution (RCE) with the privileges of the web server process. This poses a severe risk to the integrity, confidentiality, and availability of the affected system. Given that the vendor has not responded to disclosure efforts and the exploit is publicly available, the risk of active exploitation is significant.\nBecause the project operates on a rolling release basis without structured versioning, all users of the software must assume their instances are potentially vulnerable until explicit verification or manual remediation is applied.",
  "technicalDetails": "The vulnerability originates from improper input validation and the absence of file type enforcement within the manage-food.php component of the robo-cafe-rms application. Analysis indicates that the application accepts file uploads through an unknown function, likely intended for administrative food management, without implementing a whitelist-based validation mechanism.\nTechnically, the root cause is the failure of the server-side script to verify the Content-Type header or the file extension of incoming multipart/form-data requests. The application does not rename files to prevent execution or enforce storage in non-executable directories. Consequently, an attacker can bypass intended security constraints by submitting a crafted HTTP POST request containing a malicious payload disguised as a legitimate food image or data file.\nThe attack flow proceeds as follows: First, the remote attacker identifies the endpoint within manage-food.php that processes file uploads. Second, the attacker crafts a multipart request containing a malicious payload, typically a PHP web shell (e.g., webshell.php). Third, the request is sent to the target server. Because the application logic lacks sufficient inspection, it accepts the file and writes it to a publicly accessible directory within the web root. Finally, the attacker triggers the execution of the payload by navigating to the newly created URL path associated with the uploaded file. Once executed, the web shell grants the attacker the ability to execute arbitrary system commands, manipulate the underlying database, exfiltrate sensitive configuration files, or move laterally within the network infrastructure.\nThis vulnerability is particularly severe due to the lack of authentication or authorization checks surrounding the upload functionality. An attacker does not require prior access to the system or valid user credentials to initiate the upload process. The exposure is fully remote, and the exploitation process is straightforward, requiring minimal technical effort. Since the vendor has not released a patch and the exploit code is publicly disclosed, systems remain in a state of high exposure. Post-exploitation impact includes full system compromise, persistent backdoor placement, and potential data exfiltration, as the web server's service account often possesses elevated permissions relative to the application's root directory."
