漏洞描述

AccessControl provides a general security framework for use in Zope. Python's "format" functionality allows someone controlling the format string to "read" objects accessible (recursively) via attribute access and subscription from accessible objects. Those attribute accesses and subscriptions use Python's full blown `getattr` and `getitem`, not the policy restricted `AccessControl` variants `_getattr_` and `_getitem_`. This can lead to critical information disclosure. `AccessControl` already provides a safe variant for `str.format` and denies access to `string.Formatter`. However, `str.format_map` is still unsafe. Affected are all users who allow untrusted users to create `AccessControl` controlled Python code and execute it. A fix has been introduced in versions 4.4, 5.8 and 6.2. Users are advised to upgrade. There are no known workarounds for this vulnerability.

解决建议

"将组件 accesscontrol 升级至 4.4 及以上版本""将组件 zope 升级至 4.8.9 及以上版本""将组件 accesscontrol 升级至 6.2 及以上版本""将组件 zope 升级至 5.8.4 及以上版本""将组件 accesscontrol 升级至 5.8 及以上版本"
