CWE-203 通过差异性导致的信息暴露 类漏洞列表 222

CWE-203 通过差异性导致的信息暴露 类弱点 222 条 CVE 漏洞汇总,含 AI 中文分析。

CWE-203 属于可观察差异漏洞,指产品在不同情境下表现出可被未授权方察觉的差异行为或响应。攻击者常利用此特性进行侧信道分析,通过对比响应时间、错误信息或状态码,推断系统内部逻辑、验证用户身份或探测敏感数据。开发者应避免暴露细微差异,确保对合法与非法请求返回一致的错误提示和响应格式,并统一处理逻辑,从而消除可用于信息泄露的观测线索。

MITRE CWE 官方描述
CWE:CWE-203 Observable Discrepancy 英文:The product behaves differently or sends different responses under different circumstances in a way that is observable to an unauthorized actor. 译文:CWE:CWE-203 可观察差异 英文:产品在不同情况下表现出不同的行为或发送不同的响应,且这种差异对未授权实体是可观察的。
常见影响 (2)
Confidentiality, Access Control Read Application Data, Bypass Protection Mechanism
An attacker can gain access to sensitive information about the system, including authentication information that may allow an attacker to gain access to the system. Other security-relevant information about the operation or internal state of the product may be revealed to an unauthorized actor, such…
Confidentiality Read Application Data
In some cases, discrepancies can be used by attackers to form a side channel. When cryptographic primitives are vulnerable to side-channel attacks, this could be used to reveal unencrypted plaintext in the worst case.
缓解措施 (2)
Architecture and Design Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separatio…
Implementation Ensure that error messages only contain minimal details that are useful to the intended audience and no one else. The messages need to strike the balance between being too cryptic (which can confuse users) or being too detailed (which may reveal more than intended). The messages should not reveal the methods that were used to determine the error. Attackers can use detailed information to refine or…
代码示例 (2)
The following code checks validity of the supplied username and password and notifies the user of a successful or failed login.
my $username=param('username'); my $password=param('password'); if (IsValidUsername($username) == 1) { if (IsValidPassword($username, $password) == 1) { print "Login Successful"; } else { print "Login Failed - incorrect password"; } } else { print "Login Failed - unknown username"; }
Bad · Perl
"Login Failed - incorrect username or password"
Result
In this example, the attacker observes how long an authentication takes when the user types in the correct password.
def validate_password(actual_pw, typed_pw): if len(actual_pw) <> len(typed_pw): return 0 for i in len(actual_pw): if actual_pw[i] <> typed_pw[i]: return 0 return 1
Bad · Python
