CVE-2022-31195
No affected components available
DSpace open source software is a repository application which provides durable access to digital resources. In affected versions the ItemImportServiceImpl is vulnerable to a path traversal vulnerability. This means a malicious SAF (simple archive format) package could cause a file/directory to be created anywhere the Tomcat/DSpace user can write to on the server. However, this path traversal vulnerability is only possible by a user with special privileges (either Administrators or someone with command-line access to the server). This vulnerability impacts the XMLUI, JSPUI and command-line. Users are advised to upgrade. As a basic workaround, users may block all access to the following URL paths: If you are using the XMLUI, block all access to /admin/batchimport path (this is the URL of the Admin Batch Import tool). Keep in mind, if your site uses the path "/xmlui", then you'd need to block access to /xmlui/admin/batchimport. If you are using the JSPUI, block all access to /dspace-admin/batchimport path (this is the URL of the Admin Batch Import tool). Keep in mind, if your site uses the path "/jspui", then you'd need to block access to /jspui/dspace-admin/batchimport. Keep in mind, only an Administrative user or a user with command-line access to the server is able to import/upload SAF packages. Therefore, assuming those users do not blindly upload untrusted SAF packages, then it is unlikely your site could be impacted by this vulnerability.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker needs high-level or administrative privileges. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a high impact on the confidentiality of the information. There is a high impact on the integrity of the data. There is a high impact on the availability of the system.
Exploitation attempts have been detected. Elevated vigilance and prompt remediation are advised.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
A proof of concept is available for this vulnerability (1 exploit found).
