CVE 描述
Ado::Sessions versions through 0.935 for Perl generates insecure session ids
Ado::Sessions versions through 0.935 for Perl generates insecure session ids. The session id is generated from a SHA-1 hash seeded with the built-in rand function, the epoch time, and the PID. The PID will come from a small set of numbers, and the epoch time may be guessed, if it is not leaked from the HTTP Date header. The built-in rand function is unsuitable for cryptographic usage. Predicable session ids could allow an attacker to gain access to systems. Note that Ado is no longer maintained, and has been removed from the CPAN index. It is still available on BackPAN.CVE 信息
相关弱点

|---|---|---|
| Generation of Predictable Numbers or Identifiers The product uses a scheme that generates numbers or identifiers that are more predictable than required. |
||
| Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) The product uses a Pseudo-Random Number Generator (PRNG) in a security context, but the PRNG's algorithm is not cryptographically strong. |
EPSS
EPSS 是一种预测漏洞被利用可能性的评分模型。
EPSS 评分
EPSS 模型生成一个介于 0 到 1（即 0% 到 100%）之间的概率评分。评分越高，漏洞被利用的可能性越大。
EPSS 百分位
百分位用于根据 EPSS 评分对 CVE 进行排名。例如，EPSS 百分位为第 95 的 CVE，其被利用的可能性高于 95% 的其他 CVE。因此，百分位可用于比较不同 CVE 的 EPSS 评分。
