脆弱性タイトル
Nextcloud Server has a potential hash collision for background jobs could skip queuing them
ソース: NVD (National Vulnerability Database)
脆弱性説明
Nextcloud Server is a self hosted personal cloud system. MD5 hashes were used to check background jobs for their uniqueness. This increased the chances of a background job with arguments falsely being identified as already existing and not be queued for execution. By changing the Hash to SHA256 the probability was heavily decreased. It is recommended that the Nextcloud Server is upgraded to 28.0.10, 29.0.7 or 30.0.0.

Nextcloud 安全漏洞
ソース: CNNVD (China National Vulnerability Database)
脆弱性説明
Nextcloud是德国Nextcloud公司的一套开源的自托管文件同步和共享的通信应用平台。 Nextcloud存在安全漏洞，该漏洞源于MD5 哈希用于检查后台作业的唯一性。这增加了后台作业被错误地识别为已经存在且未排队执行的可能性。通过将哈希更改为 SHA256，可能性大大降低。
