Vulnerability Title
Logback deserialization whitelist bypass for java.lang and java.util
Vulnerability Description
Deserialization of untrusted data vulnerability in QOS.CH Sarl logback logback-core (HardenedObjectInputStream (logback-core) modules) allows Object Injection albeit heavily restricted.
More precisely, an attacker able to influence serialized data sent to
SimpleSocketServer or SimpleSSLSocketServer can instantiate objects from
classes in the java.lang and java.util packages that are not explicitly
blocked.
Although deserialization is heavily restricted by HardenedObjectInputStream and no
practical way to achieve remote code execution or significant privilege
escalation has been identified, this issue constitutes a bypass of the
intended security restrictions.
This issue affects logback: through 1.5.32 inclusive.

可信数据的反序列化
Vulnerability Title
logback-core 安全漏洞
Vulnerability Description
logback-core是QOS.CH开源的一个日志框架的核心模块。 logback-core 1.5.32及之前版本存在安全漏洞,该漏洞源于HardenedObjectInputStream模块中反序列化不可信数据,可能导致对象注入,尽管受到严格限制,但能够影响发送到SimpleSocketServer或SimpleSSLSocketServer的序列化数据的攻击者可实例化java.lang和java.util包中未明确阻止的类对象,构成对预期安全限制的绕过。
