Apache Software Foundation Apache Roller
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.
Apache Roller 6.1.5 存在对 XML 外部实体引用限制不当的漏洞。拥有博客条目编辑权限的用户可诱使服务器使用未禁用外部实体解析的 XML 解析器来解析受攻击者影响的 trackback 响应，从而导致披露 Roller 进程可读取的文件内容。虽然 Trackback 功能在标准用户界面中被隐藏，但其操作仍可直接访问，且无需任何非默认的服务器配置即可利用。建议用户升级至 Apache Roller 6.1.6 或更高版本，该版本已移除外发 trackback 响应解析器，从而修复此漏洞。

Vulnerability Title
Apache Roller: XML external entity processing in trackback response parser
Source: CVE Program / CVE List V5
Vulnerability Description
Improper Restriction of XML External Entity Reference in Apache Roller 6.1.5 allows a user with entry-editing rights on a weblog to cause the server to parse an attacker-influenced trackback response with an XML parser that does not disable external entity resolution, leading to disclosure of files readable by the Roller process. The Trackback control is hidden in the standard UI, but its action remains directly reachable, and no non-default server configuration is required. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which removes the outbound trackback response parser.
