CVE-2025-62792 (GCVE-0-2025-62792)
Vulnerability from cvelistv5 – Published: 2025-10-29 16:50 – Updated: 2025-10-29 18:10
VLAI?
Summary
Wazuh is a free and open source platform used for threat prevention, detection, and response. Prior to 4.12.0, a buffer over-read occurs in w_expression_match() when strlen() is called on str_test, because the corresponding buffer is not being properly NULL terminated during its allocation in OS_CleanMSG(). A compromised agent can cause a READ operation beyond the end of the allocated buffer (which may contain sensitive information) by sending a specially crafted message to the wazuh manager. An attacker who is able to craft and send an agent message to the wazuh manager can cause a buffer over-read and potentially access sensitive data. This vulnerability is fixed in 4.12.0.

Summary
Wazuh is a free and open source platform used for threat prevention, detection, and response. Prior to 4.11.0, DecodeCiscat() implementation does not check the return the value of cJSON_GetObjectItem() for a possible NULL value in case of an error. A compromised agent can cause a crash of analysisd by sending a specially crafted message to the wazuh manager. An attacker who is able to craft and send an agent message to the wazuh manager can cause analysisd to crash and make it unavailable. This vulnerability is fixed in 4.11.0.

Summary
Wazuh is a free and open source platform used for threat prevention, detection, and response. Prior to 4.11.0, w_copy_event_for_log() references memory (initially allocated in OS_CleanMSG()) after it has been freed. A compromised agent can potentially compromise the integrity of the application by sending a specially crafted message to the wazuh manager. An attacker who is able to craft and send an agent message to the wazuh manager can leverage this issue to potentially compromise the integrity of the application (the use of previously freed memory may corrupt valid data, if the memory area in question has been allocated and used properly elsewhere). This vulnerability is fixed in 4.11.0.

CVE-2025-62787 (GCVE-0-2025-62787)
Vulnerability from cvelistv5 – Published: 2025-10-29 16:30 – Updated: 2025-10-29 17:38
VLAI?
Summary
Wazuh is a free and open source platform used for threat prevention, detection, and response. Prior to 4.10.2, a buffer over-read occurs in DecodeWinevt() when child_attr[p]->attributes[j] is accessed, because the corresponding index (j) is incorrect. A compromised agent can cause a READ operation beyond the end of the allocated buffer (which may contain sensitive information) by sending a specially crafted message to the wazuh manager. An attacker who is able to craft and send an agent message to the wazuh manager can cause a buffer over-read and potentially access sensitive data. While the buffer over-read is always triggered while resolving the arguments of mdebug2, specific configuration options (analysisd.debug=2) need to be in place for the respective data to be leaked. This vulnerability is fixed in 4.10.2.

CVE-2025-62786 (GCVE-0-2025-62786)
Vulnerability from cvelistv5 – Published: 2025-10-29 15:52 – Updated: 2025-10-29 16:20
VLAI?
Summary
Wazuh is a free and open source platform used for threat prevention, detection, and response. A heap-based out-of-bounds WRITE occurs in decode_win_permissions, resulting in writing a NULL byte 2 bytes before the start of the buffer allocated to decoded_it. A compromised agent can potentially leverage this issue to perform remote code execution, by sending a specially crafted message to the wazuh manager. An attacker who is able to craft and send an agent message to the wazuh manager can leverage this issue to potentially achieve remote code execution on the wazuh manager (the exploitability of this vulnerability depends on the specifics of the respective heap allocator). This vulnerability is fixed in 4.10.2.
Severity ?

CVE-2024-1243 (GCVE-0-2024-1243)
Vulnerability from cvelistv5 – Published: 2025-06-11 01:15 – Updated: 2025-06-11 14:25
VLAI?
Summary
Improper input validation in the Wazuh agent for Windows prior to version 4.8.0 allows an attacker with control over the Wazuh server or agent key to configure the agent to connect to a malicious UNC path. This results in the leakage of the machine account NetNTLMv2 hash, which can be relayed for remote code execution or used to escalate privileges to SYSTEM via AD CS certificate forging and other similar attacks.

Starting in version 4.4.0 and prior to version 4.9.1, an unsafe deserialization vulnerability allows for remote code execution on Wazuh servers. DistributedAPI parameters are a serialized as JSON and deserialized using `as_wazuh_object` (in `framework/wazuh/core/cluster/common.py`). If an attacker manages to inject an unsanitized dictionary in DAPI request/response, they can forge an unhandled exception (`__unhandled_exc__`) to evaluate arbitrary python code. The vulnerability can be triggered by anybody with API access (compromised dashboard or Wazuh servers in the cluster) or, in certain configurations, even by a compromised agent. Version 4.9.1 contains a fix.

Summary
Wazuh is a free and open source platform used for threat prevention, detection, and response. It is capable of protecting workloads across on-premises, virtualized, containerized, and cloud-based environments. The wazuh-agent for Windows is vulnerable to a Local Privilege Escalation vulnerability due to improper ACL of the non-default installation directory. A local malicious user could potentially exploit this vulnerability by placing one of the many DLL that are loaded and not present on the system in the installation folder of the agent OR by replacing the service executable binary itself with a malicious one. The root cause is an improper ACL applied on the installation folder when a non-default installation path is specified (e.g,: C:\wazuh). Many DLLs are loaded from the installation folder and by creating a malicious DLLs that exports the functions of a legit one (and that is not found on the system where the agent is installed, such as rsync.dll) it is possible to escalate privileges from a low-privileged user and obtain code execution under the context of NT AUTHORITY\SYSTEM. This issue has been addressed in version 4.9.0 and all users are advised to upgrade. There are no known workarounds for this vulnerability.

Vulnerability from cvelistv5 – Published: 2024-04-19 14:28 – Updated: 2024-08-02 22:16
VLAI?
Summary
Wazuh is a free and open source platform used for threat prevention, detection, and response. A wrong validation in the `host_deny` script allows to write any string in the `hosts.deny` file, which can end in an arbitrary command execution on the target system. This vulnerability is part of the active response feature, which can automatically triggers actions in response to alerts. By default, active responses are limited to a set of pre defined executables. This is enforced by only allowing executables stored under `/var/ossec/active-response/bin` to be run as an active response. However, the `/var/ossec/active-response/bin/host_deny` can be exploited. `host_deny` is used to add IP address to the `/etc/hosts.deny` file to block incoming connections on a service level by using TCP wrappers. Attacker can inject arbitrary command into the `/etc/hosts.deny` file and execute arbitrary command by using the spawn directive. The active response can be triggered by writing events either to the local `execd` queue on server or to the `ar` queue which forwards the events to agents. So, it can leads to LPE on server as root and RCE on agent as root. This vulnerability is fixed in 4.7.2.

"value": "Wazuh is a free and open source platform used for threat prevention, detection, and response. A wrong validation in the `host_deny` script allows to write any string in the `hosts.deny` file, which can end in an arbitrary command execution on the target system. This vulnerability is part of the active response feature, which can automatically triggers actions in response to alerts. By default, active responses are limited to a set of pre defined executables. This is enforced by only allowing executables stored under `/var/ossec/active-response/bin` to be run as an active response. However, the `/var/ossec/active-response/bin/host_deny` can be exploited. `host_deny` is used to add IP address to the `/etc/hosts.deny` file to block incoming connections on a service level by using TCP wrappers. Attacker can inject arbitrary command into the `/etc/hosts.deny` file and execute arbitrary command by using the spawn directive. The active response can be triggered by writing events either to the local `execd` queue on server or to the `ar` queue which forwards the events to agents. So, it can leads to LPE on server as root and RCE on agent as root. This vulnerability is fixed in 4.7.2."

CVE-2023-49275 (GCVE-0-2023-49275)
Vulnerability from cvelistv5 – Published: 2024-04-19 14:24 – Updated: 2024-08-02 21:53

Summary
Wazuh is a free and open source platform used for threat prevention, detection, and response. A NULL pointer dereference was detected during fuzzing of the analysis engine, allowing malicious clients to DoS the analysis engine. The bug occurs when `analysisd` receives a syscollector message with the `hotfix` `msg_type` but lacking a `timestamp`. It uses `cJSON_GetObjectItem()` to get the `timestamp` object item and dereferences it without checking for a `NULL` value. A malicious client can DoS the analysis engine. This vulnerability is fixed in 4.7.1.
