Vulnerability Title
MISP Missing Authorization in Cryptographic Key View Exposes Signing Keys from Protected Events
Vulnerability Description
Affected versions of MISP do not enforce parent-event visibility when serving cryptographic keys through CryptographicKeysController::view().
The vulnerable handler queried CryptographicKey directly using the supplied key ID and selected sensitive fields such as:
*
type
*
key_data
*
fingerprint
but did not fetch or authorize the associated parent event first.
The upstream commit explicitly states that cryptographicKeys/view could return a protected event’s signing key to any authenticated user.
The fix adds parent_id and parent_type to the lookup and then enforces authorization through the associated event using fetchSimpleEvent($user, parent_id). If the parent is not an Event, access is limited to site administrators.
Version affected: ≤2.5.45

MISP 授权问题漏洞
Vulnerability Description
MISP是MISP组织开源的一个威胁情报共享与分析平台。 MISP 2.5.45及之前版本存在授权问题漏洞,该漏洞源于通过CryptographicKeysController::view()提供加密密钥时未强制父事件可见性,直接使用密钥ID查询敏感字段而未先授权关联父事件,可能导致经过身份验证的用户获取受保护事件的签名密钥。
