Quick assessment

Affected
jahlives openssl_encrypt
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

以下是对该漏洞描述的中文翻译： **OpenSSL 1.4.9 之前的 功能未能对导入的身份文档（identity document）中的 email 字段进行净化（sanitize），允许攻击者通过注入 ANSI 转义序列来伪造向用户显示的指纹验证行。攻击者可以通过正常的联系人交换流程或密钥服务器（keyserver）响应，投递一个经过构造的身份数据束（identity bundle），从而操纵终端输出并显示一个虚假的指纹，进而绕过保护用户免受密钥替换攻击的带外（out-of-band）验证机制。

Vulnerability Title
openssl_encrypt before 1.4.9 ANSI Escape Injection via Identity Email
Source: CVE Program / CVE List V5
Vulnerability Description
openssl_encrypt before 1.4.9 fails to sanitize the email field of imported identity documents, allowing attackers to inject ANSI escape sequences that forge the fingerprint verification line displayed to users. Attackers can deliver a crafted identity bundle through normal contact-exchange flows or keyserver responses to manipulate terminal output and display a fraudulent fingerprint, bypassing the out-of-band verification mechanism that protects against key substitution attacks.
