User Interaction: None
Impact: System Compromise, Data Leakage

Affected Products

Product | Affected Versions

Jenkins Git Parameter Plugin | 439.vb_0e46ca_14534 and earlier

How the Exploit Works

This vulnerability arises from the lack of input validation in the Jenkins Git Parameter Plugin. When a Git parameter value is submitted to the build, the plugin does not verify that the submitted value matches one of the offered choices. This lack of validation allows an attacker with Item/Build permission to inject arbitrary values into Git parameters, potentially leading to execution of unintended commands or access to sensitive information.

Conceptual Example Code

The following is a hypothetical example of how the vulnerability might be exploited:

POST /jenkins/build HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"gitParameters": {
"choices": ["master", "develop"],
"selected": "master; rm -rf /"
}
}

In this example, an attacker submits a build request with a malicious `selected` value. Instead of a legitimate branch name, the attacker injects a command to delete all files in the root directory (`rm -rf /`). This command could cause significant damage to the Jenkins server if executed.

Remediation

To remediate this vulnerability, apply the latest patch provided by the vendor. If the patch cannot be applied immediately, consider using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to filter out malicious requests as a temporary mitigation. Note, however, that these are not long-term solutions, and patching the vulnerability should be prioritized.

Overview

The cybersecurity world is fluctuating once again as a new vulnerability has surfaced: CVE-2025-36600. This vulnerability resides in the BIOS of Dell client platforms, making it an issue that affects a wide range of users across various organizations and industries. The severity of the situation is accentuated by the potential for high privileged attackers to exploit this vulnerability and execute arbitrary code on the compromised system.
The gravity of this vulnerability lies in its impact on data integrity and confidentiality. If successfully exploited, attackers can gain control of the system, leading to possible data leakage or system compromise. As such, it’s crucial to understand the details of this vulnerability and implement appropriate mitigation measures to secure affected systems.

Vulnerability Summary

CVE ID: CVE-2025-36600
Severity: High (CVSS: 8.2)
Attack Vector: Local
Privileges Required: High
User Interaction: None
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

Dell Client Platform BIOS | All current versions

How the Exploit Works

The crux of the CVE-2025-36600 vulnerability lies in the improper access control applied to mirrored or aliased memory regions in Dell’s BIOS. This flaw allows an attacker with local access and high privileges to manipulate the mirrored or aliased memory regions. The attacker can then place malicious code within these memory regions, leading to unauthorized code execution.

Conceptual Example Code

Below is a conceptual example of how an attacker might exploit this vulnerability. This is highly simplified and intended for illustrative purposes only:

# Exploit via shell command
echo 'malicious_code' > /dev/mem

In this example, the attacker writes a malicious code directly into the memory via shell command. This code could then be executed, leading to the compromise of the system.

Mitigation Guidance

To mitigate this vulnerability, Dell has recommended applying the vendor patch as soon as it becomes available. This will alter the access controls applied to mirrored or aliased memory regions, preventing unauthorized modifications.
In the interim, users can use Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) as temporary mitigation. These tools can help in detecting and blocking malicious activities related to this vulnerability. However, they should not be considered a long-term solution, as they do not address the underlying vulnerability in the BIOS.

Overview

The CVE-2025-21427 vulnerability represents a significant threat to data privacy and system integrity. It allows for information disclosure during the decoding of RTP (Real-Time Transport Protocol) packet payload when the User Equipment (UE) receives an RTP packet from the network. This vulnerability can lead to potential system compromise or data leakage, affecting any system or network reliant on the secure transmission of RTP data packets. Given the widespread use of RTP in real-time applications, such as audio and video streaming, understanding and mitigating this vulnerability is of utmost importance.

Vulnerability Summary

CVE ID: CVE-2025-21427

How the Exploit Works

The exploit takes advantage of a flaw in the decoding process of RTP packet payload. When a UE receives an RTP packet from the network, it decodes the packet payload. However, due to the vulnerability, the decoding process fails to properly handle certain data, leading to an unauthorized disclosure of information. This information can potentially be leveraged by an attacker to compromise the system or leak sensitive data.

Conceptual Example Code

Below is a conceptual example of a malformed RTP packet that could potentially exploit this vulnerability. Please note that this is a hypothetical scenario intended for illustration purposes only.

POST /rtp/packet/decode HTTP/1.1
Host: target.example.com
Content-Type: application/rtp
{
"RTP_Packet": "malformed_packet_data..."
}

Mitigation

The primary mitigation for this vulnerability is to apply the vendor patch as soon as it becomes available. In the event that the vendor patch is not immediately available or applicable, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation strategy. They can be configured to monitor and block suspicious RTP packets, reducing the risk of exploitation. However, these measures are not a substitute for patching the vulnerability at the source and should only be considered as interim solutions.

Overview

CVE-2025-24003 is a highly severe vulnerability that allows an unauthenticated remote attacker to exploit charging stations that comply with the German Calibration Law (Eichrecht). The vulnerability lies in the handling of MQTT messages, which can trigger out-of-bounds writes in the charging stations. This vulnerability particularly affects EichrechtAgents, leading to a loss of integrity and potentially causing a denial-of-service for these stations. Given the widespread reliance on charging stations in today’s environmentally conscious world, this vulnerability presents a significant risk that needs to be addressed urgently to prevent widespread disruption and potential data leakage.

Impact: Loss of integrity for EichrechtAgents, potential denial-of-service for affected charging stations, and potential system compromise or data leakage.

Affected Products

Product | Affected Versions

Charging stations complying with Eichrecht | All Versions

How the Exploit Works

The exploit takes advantage of the improper handling of MQTT messages by the affected charging stations. An unauthenticated remote attacker can send specially crafted MQTT messages to the charging station. These messages can trigger out-of-bounds writes, corrupting data and causing unexpected behavior. This could potentially lead to a loss of integrity for EichrechtAgents and a potential denial-of-service for the charging stations. In extreme cases, this vulnerability could even lead to system compromise or data leakage.

Conceptual Example Code

Here’s a conceptual representation of how the vulnerability might be exploited. This example assumes that the attacker knows the IP address of the charging station and is able to send MQTT messages to it.

# An attacker might use a tool like mosquitto_pub to publish a malicious MQTT message:
mosquitto_pub -h <charging_station_ip> -t <topic> -m '{ "malicious_payload": "..." }'

Please note that this is a hypothetical example and the actual exploit could be more complex, depending on the specific implementation of the charging station and the MQTT protocol.

Mitigation Guidance

To mitigate this vulnerability, it is recommended to apply the vendor patch as soon as it becomes available. In the interim, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure. These tools can potentially detect and block malicious MQTT messages, reducing the risk of exploitation. It’s also advisable to monitor network traffic for any unusual activity, particularly involving MQTT messages.
