CWE-263 口令老化拥有过长有效期 类漏洞列表 1

CWE-263 口令老化拥有过长有效期 类弱点 1 条 CVE 漏洞汇总,含 AI 中文分析。

CWE-263 属于密码策略配置不当漏洞,指系统虽实施密码老化机制,但过期周期设置过长。攻击者利用此缺陷,在漫长的有效期内进行离线密码破解或暴力攻击,从而窃取凭证。开发者应通过定期安全评估,将密码最大有效期限制在合理范围内(如90天以内),并配合强复杂度要求,以缩短攻击窗口,降低凭证泄露风险。

MITRE CWE 官方描述
CWE:CWE-263 密码老化(Password Aging)过期时间过长 英文:该产品支持密码老化(Password Aging),但过期时间过长。 密码老化(Password Aging,或密码轮换 Password Rotation)是一项策略,要求用户在经过定义的时间段后更改密码,例如每 30 或 90 天。过长的过期时间会为攻击者在强制用户更改为新密码之前进行密码破解(Password Cracking)提供更多时间。需要注意的是,虽然密码老化(Password Aging)曾被视为一项重要的安全特性,但如今已不再受到许多人的青睐,因为与其他机制(如慢速哈希 Slow Hashes)相比,它针对现代威胁的有效性较低。此外,强制频繁更改密码可能会无意中鼓励用户选择安全性较低的密码。然而,由于合规性要求等因素(例如支付卡行业数据安全标准 Payment Card Industry Data Security Standard (PCI DSS)),密码老化(Password Aging)仍在使用。

缓解措施 (5)
ImplementationPreviously, "password expiration" was widely advocated as a defense-in-depth approach to minimize the risk of weak passwords, and it has become a common practice. Password expiration requires a password to be changed within a fixed time window (such as every 90 days). However, this approach has significant limitations in the current threat landscape, and…
Architecture and DesignEnsure that password aging is limited so that there is a defined maximum age for passwords. Note that if the expiration window is too short, it can cause users to generate poor or predictable passwords.
Architecture and DesignEnsure that the user is notified several times leading up to the password expiration.
Architecture and DesignCreate mechanisms to prevent users from reusing passwords or creating similar passwords.
ImplementationDevelopers might disable clipboard paste operations into password fields as a way to discourage users from pasting a password into a clipboard. However, this might encourage users to choose less-secure passwords that are easier to type, and it can reduce the usability of password managers [REF-1294].
Effectiveness: Discouraged Common Practice

A system requires the changing of passwords every five years.
