XML External Entity injection in Sparx Enterprise Architect

Enterprise Architect is vulnerable to XML External Entity (XXE) injection in the XSLT Debugger feature. When a user loads a crafted XML file containing a `DOCTYPE` with an external DTD reference, the parser processes external entities, allowing an attacker to read arbitrary files from the victim's filesystem. Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 17.1 but may also affect other versions.

Sparx Pro Cloud Server reveals sensitive information to an unauthenticated user

Exposure of Private Personal Information to an Unauthorized Actor, : Exposure of Sensitive System Information to an Unauthorized Control Sphere vulnerability in Sparx Systems Pty Ltd. Sparx Pro Cloud Server. Unauthenticated user can retrieve database password in plaintext in certain situations

Plaintext Storage of a Password in Sparx Pro Cloud Server.

Plaintext Storage of a Password vulnerability in Sparx Systems Pty Ltd. Sparx Pro Cloud Server.  In a setup where OpenID is used as the primary method of authentication to authenticate to Sparx EA, Pro Cloud Server creates local passwords to the users and stores them in plaintext.

Race Condition in Sparx Pro Cloud Server

Sparx Pro Cloud Server is vulnerable to a Race Condition in the /data_api/dl_internal_artifact.php endpoint. The application downloads the properties of the object pointed by guid parameter and saves loaded content in current location (__DIR__) under the specified name. An attacker with repository access can control both the filename and file contents, allowing the creation of a malicious PHP file in a current directory. Although the file is deleted after processing, a race condition exists: if the response transmission is delayed (e.g., via a large file or slow client connection), the file remains accessible. During this window, the attacker can issue a second request to execute the malicious PHP file, resulting in remote code execution. The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only version 6.1 (build 167) and below were tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.

Authentication Bypass in Sparx Pro Cloud Server

Sparx Pro Cloud Server requires authentication based on requested URL. An attacker can omit the "model" query parameter and send the model name only in the binary blob in POST request allowing SQL query execution without authentication. The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only version 6.1 (build 167) and below were tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.

Broken Access Control in Sparx Pro Cloud Server

Sparx Pro Cloud Server is vulnerable to Broken Access Control within communication with the database. Due to lack of permission checks, any low privileged user can run arbitrary SQL queries within database user context. The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only version 6.1 (build 167) and below were tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.

DoS in Sparx Pro Cloud Server

Improper Handling of Syntactically Invalid Structure in Sparx Pro Cloud Server allows Denial of Service (DoS) attack to be executed by sending an specially crafted SQL query. This causes the Pro Cloud Server service to terminate unexpectedly.  The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only version 6.1 (build 167) and below were tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.

Authorization Bypass in Sparx Enterprise Architect

Sparx Enterprise Architect software has a security feature that limits user's actions to those specified in the role. An authenticated attacker can modify the Enterprise Architect client behavior (e.g. using a debugger) and log in as any other user or administrator - then it is possible to do every possible change to the repository. The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only version 17.1 and below were tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.
