Common Weakness Enumeration
CWE-364
Weakness AllowedSignal Handler Race Condition
Abstraction: Base · Status: Incomplete
The product uses a signal handler that introduces a race condition.
These issues occur when non-reentrant functions, or state-sensitive actions occur in the signal handler, where they may be called at any time. These behaviors can violate assumptions being made by the "regular" code that is interrupted, or by other signal handlers that may also be invoked. If these functions are called at an inopportune moment - such as while a non-reentrant function is already running - memory corruption could occur that may be exploitable for code execution. Another signal race condition commonly found occurs when free() is called within a signal handler, resulting in a double free and therefore a write-what-where condition. Even if a given pointer is set to NULL after it has been freed, a race condition still exists between the time the memory was freed and the pointer was set to NULL. This is especially problematic if the same signal handler has been set for more than one signal -- since it means that the signal handler itself may be reentered.
There are several known behaviors related to signal handlers that have received the label of "signal handler race condition":
Shared state (e.g. global data or static variables) that are accessible to both a signal handler and "regular" code
Shared state between a signal handler and other signal handlers
Use of non-reentrant functionality within a signal handler - which generally implies that shared state is being used. For example, malloc() and free() are non-reentrant because they may use global or static data structures for managing memory, and they are indirectly used by innocent-seeming functions such as syslog(); these functions could be exploited for memory corruption and, possibly, code execution.
Association of the same signal handler function with multiple signals - which might imply shared state, since the same code and resources are accessed. For example, this can be a source of double-free and use-after-free weaknesses.
Use of setjmp and longjmp, or other mechanisms that prevent a signal handler from returning control back to the original functionality
While not technically a race condition, some signal handlers are designed to be called at most once, and being called more than once can introduce security problems, even when there are not any concurrent calls to the signal handler. This can be a source of double-free and use-after-free weaknesses.
Signal handler vulnerabilities are often classified based on the absence of a specific protection mechanism, although this style of classification is discouraged in CWE because programmers often have a choice of several different mechanisms for addressing the weakness. Such protection mechanisms may preserve exclusivity of access to the shared resource, and behavioral atomicity for the relevant code:
Avoiding shared state
Using synchronization in the signal handler
Using synchronization in the regular code
Disabling or masking other signals, which provides atomicity (which effectively ensures exclusivity)
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.
Relationships and members
Modes of introduction
Implementation
Race conditions frequently occur in signal handlers, since signal handlers support asynchronous actions.
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.)

Title
Strapi core vulnerable to sensitive data exposure via CORS misconfiguration
Summary
Strapi is an open source headless content management system. Strapi versions prior to 5.20.0 contain a CORS misconfiguration vulnerability in default installations. By default, Strapi reflects the value of the Origin header back in the Access-Control-Allow-Origin response header without proper validation or whitelisting. This allows an attacker-controlled site to send credentialed requests to the Strapi backend. An attacker can exploit this by hosting a malicious site on a different origin (e.g., different port) and sending requests with credentials to the Strapi API. The vulnerability is fixed in version 5.20.0. No known workarounds exist.

Title
Systemd-coredump: race condition that allows a local attacker to crash a suid program and gain read access to the resulting core dump
Summary
A vulnerability was found in systemd-coredump. This flaw allows an attacker to force a SUID process to crash and replace it with a non-SUID binary to access the original's privileged process coredump, allowing the attacker to read sensitive data, such as /etc/shadow content, loaded by the original process.
A SUID binary or process has a special type of permission, which allows the process to run with the file owner's permissions, regardless of the user executing the binary. This allows the process to access more restricted data than unprivileged users or processes would be able to. An attacker can leverage this flaw by forcing a SUID process to crash and force the Linux kernel to recycle the process PID before systemd-coredump can analyze the /proc/pid/auxv file. If the attacker wins the race condition, they gain access to the original's SUID process coredump file. They can read sensitive content loaded into memory by the original binary, affecting data confidentiality.

Title
Openssh: possible remote code execution due to a race condition in signal handling affecting red hat enterprise linux 9
Summary
A race condition vulnerability was discovered in how signals are handled by OpenSSH's server (sshd). If a remote attacker does not authenticate within a set time period, then sshd's SIGALRM handler is called asynchronously. However, this signal handler calls various functions that are not async-signal-safe, for example, syslog(). As a consequence of a successful attack, in the worst case scenario, an attacker may be able to perform a remote code execution (RCE) as an unprivileged user running the sshd server.

Title
Openssh: regresshion - race condition in ssh allows rce/dos
Summary
A security regression (CVE-2006-5051) was discovered in OpenSSH's server (sshd). There is a race condition which can lead sshd to handle some signals in an unsafe manner. An unauthenticated, remote attacker may be able to trigger it by failing to authenticate within a set time period.

If this mitigation is implemented, it is highly recommended to use a tool like \u0027fail2ban\u0027 alongside a firewall to monitor log files and manage connections appropriately.\n\nIf any of the mitigations mentioned above is used, please note that the removal of LoginGraceTime parameter from sshd_config is not automatic when the updated package is installed."

Summary
Signal Handler Race Condition vulnerability in Mitsubishi Electric India GC-ENET-COM whose first 2 digits of 11-digit serial number of unit are "16" allows a remote unauthenticated attacker to cause a denial-of-service (DoS) condition in Ethernet communication by sending a large number of specially crafted packets to any UDP port when GC-ENET-COM is configured as a Modbus TCP Server. The communication resumes only when the power of the main unit is turned off and on or when the GC-ENET-COM is hot-swapped from the main unit.

Mitigation MIT-3
Requirements
Strategy: Language Selection
Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Mitigation
Architecture and Design
Design signal handlers to only set flags, rather than perform complex functionality. These flags can then be checked and acted upon within the main program loop.
Mitigation
Implementation
Only use reentrant functions within signal handlers. Also, use validation to ensure that state is consistent while performing asynchronous actions that affect the state of execution.
No CAPEC attack patterns related to this CWE.
