CWE-253
Weakness AllowedIncorrect Check of Function Return Value
Abstraction: Base · Status: Incomplete
The product incorrectly checks a return value from a function, which prevents it from detecting errors or exceptional conditions.
Mapping guidance
This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
Modes of introduction
Detection methods
Automated Static Analysis
Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)

From 3.0.5 until 3.0.17, the PCRE2 implementation of @rxGlobal in src/utils/regex.cc converts pcre2_match match-limit errors into an ordinary no-match result instead of propagating a non-OK RegexResult. When attacker-controlled input exhausts SecPcreMatchLimit, rules that rely on MSC_PCRE_LIMITS_EXCEEDED or its TX compatibility indicator do not run, so a request that should be rejected can pass through the WAF. The issue affects PCRE2 deployments that use @rxGlobal with a limit-exhaustible expression and a compensating rule; it is not a universal WAF bypass. This issue is fixed in version 3.0.17."

Mitigation
Strategy: Language Selection
Use a language or compiler that uses exceptions and requires the catching of those exceptions.
Mitigation
Properly check all functions which return a value.
Mitigation
When designing any function make sure you return a value or throw an exception in case of an error.
No CAPEC attack patterns related to this CWE.
