Quick assessment

Affected
DSpace DSpace
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

DSpace是DSpace组织的一个数字资产管理系统。 DSpace 8.0-rc1至8.4之前版本、9.0-rc1至9.3之前版本和10-rc1至10.0之前版本存在路径遍历漏洞，该漏洞源于COAR Notify / LDN服务在读取“inbound pattern”/“template”文件输入流时未检查路径遍历或限制模板到已知基础路径，可能导致具有管理员凭据的攻击者读取文件系统其他位置的不受信任文件并将其解释为Apache Velocity模板。

Vulnerability Title
DSpace: Path Traversal possible in LDN message generation
Source: CVE Program / CVE List V5
Vulnerability Description
DSpace open source software is a repository application which provides durable access to digital resources. From versions 8.0-rc1 to before 8.4, 9.0-rc1 to before 9.3, and 10-rc1 to before 10.0, a path traversal vulnerability is possible via the COAR Notify / LDN service in DSpace. The attacker MUST already have DSpace administrator credentials in order to perform the attack. When reading a file input stream of an "inbound pattern" / "template", used to generate an LDN message, the LDN class does not check for path traversal or restrict the templates to a known base path. This could allow an untrusted file from elsewhere in the file system (e.g. an export log, a bitstream path, a temporary file) to be read and interpreted as an Apache Velocity template. This issue has been patched in versions 8.4, 9.3, and 10.0.
