7.6.4
CVE-2025-53621 describes two related XML External Entity (XXE) injection vulnerabilities discovered in the DSpace API. These vulnerabilities allow attackers to potentially read sensitive files or, in some scenarios, execute arbitrary code. The issue impacts DSpace versions prior to 7.6.4, 8.2, and 9.1, arising from improper handling of XML parsing during archive imports and external API responses. A fix is available in DSpace 7.6.4.

Impacto y Escenarios de Ataquetraduciendo…
Successful exploitation of CVE-2025-53621 could allow an attacker to read arbitrary files from the server's filesystem. This includes potentially accessing configuration files, database credentials, or other sensitive data. The first vulnerability arises during the import of archives using the Simple Archive Format, either through the command line (./dspace import) or the user interface. The second vulnerability stems from parsing XML responses from external sources. While direct remote code execution is not guaranteed, the ability to read local files significantly increases the attack surface and could be a stepping stone for further exploitation, such as privilege escalation or data exfiltration. The impact is amplified in environments where DSpace is used to manage sensitive research data or institutional repositories.
Contexto de Explotacióntraduciendo…
The vulnerability was published on 2025-07-15. Currently, there's no indication of this CVE being on KEV or having a high EPSS score. Public proof-of-concept (POC) code is not yet widely available, but the XXE nature of the vulnerability makes it likely that such exploits will emerge. Active campaigns targeting DSpace are not currently reported, but the ease of exploitation once a POC is available warrants vigilance.

Mitigación y Workaroundstraduciendo…
The primary mitigation for CVE-2025-53621 is to upgrade to DSpace version 7.6.4 or later. If an immediate upgrade is not feasible, consider implementing temporary workarounds. Disable external entity resolution within the DSpace import process by configuring XML parsing libraries to explicitly disallow external entities. Restrict access to the dspace import command to trusted users only. Carefully review and validate all XML responses received from external sources before processing them within DSpace. After upgrading, confirm the fix by attempting an archive import and verifying that external entity resolution is disabled.
Cómo corregirlotraduciendo…
Actualice DSpace a la versión 7.6.4, 8.2 o 9.1. Si no puede actualizar inmediatamente, aplique el parche manualmente proporcionado por DSpace. Inspeccione cuidadosamente los archivos SAF antes de importarlos y deshabilite los servicios externos afectados para mitigar la vulnerabilidad.
