Impact: System compromise and potential data leakage

Affected Products

Product | Affected Versions

Trend Micro Security | 17.8 (Consumer version)

How the Exploit Works

The exploit takes advantage of a link following vulnerability in Trend Micro Security 17.8. An attacker, with local access to the system, can manipulate symbolic links to redirect or delete privileged files. This can lead to the system’s security being compromised or sensitive data being leaked. The vulnerability requires user interaction and low-level privileges, making it a potent threat if an attacker can convince a user to perform certain actions or execute specific files.

Conceptual Example Code

Here’s a conceptual example of how the vulnerability might be exploited using a shell command:
```
# Attacker creates a symbolic link to a privileged file
ln -s /path/to/privilegedfile /path/to/symlink
# Then the attacker tricks the user into deleting the symlink
rm /path/to/symlink
```
In this scenario, if the application doesn’t validate or resolve the symbolic link properly, the actual privileged file will be deleted instead of the symlink.

Mitigation Guidance

The best course of action to mitigate this vulnerability is to apply the patch provided by the vendor. If the patch is not yet available, a web application firewall (WAF) or intrusion detection system (IDS) could offer temporary protection by monitoring and possibly blocking suspicious activities. However, these are temporary measures and do not substitute for properly patching the system.

User Interaction: Required
Impact: Potential system compromise and data leakage

Affected Products

Product | Affected Versions

Fuji Electric Smart Editor | Versions prior to 3.5.3

How the Exploit Works

The vulnerability stems from a stack-based buffer overflow issue within the Smart Editor. A buffer overflow occurs when more data is written to a block of allocated memory (buffer) than it can hold. In the case of a stack-based buffer overflow, this extra data overflows into adjacent memory locations on the stack.
An attacker can exploit this vulnerability by sending a specially crafted payload to the application. If the payload is processed by the Smart Editor, it can cause the buffer overflow, corrupting the adjacent memory locations. This allows the attacker to overwrite other data on the stack, potentially leading to arbitrary code execution.

Conceptual Example Code

Below is a conceptual example of a malicious payload that might be sent to exploit the vulnerability. This is a simple illustration and actual exploitation would require tailoring the payload to the specific environment and target:
```
POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_payload": "AAAAAAAAAAAA...[continues beyond buffer size]...BBBB" }
```
In this example, “A”s represent the data exceeding the buffer size, causing an overflow, and “B”s represent the attacker’s malicious code that could be executed as a result of the overflow.

Recommendations for Mitigation

Fuji Electric has released a patch for this vulnerability, so the primary mitigation strategy should be to apply this patch immediately. If immediate patching isn’t possible, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can provide temporary mitigation by identifying and blocking attempts to exploit the vulnerability. However, these should only be considered temporary measures, and patching the software should always be the primary defense. Regularly updating and patching your software is a fundamental cyber hygiene habit that significantly reduces your risk of falling victim to such vulnerabilities.

Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

Fuji Electric Smart Editor | All versions prior to the latest patch

How the Exploit Works

The unchecked buffer vulnerability in Fuji Electric Smart Editor involves an out-of-bound read error. This error occurs when the software reads data past the end, or before the start, of the intended buffer. This can lead to corruption of relevant memory, and can potentially allow an attacker to execute arbitrary code. The vulnerability is triggered when a specially crafted file is loaded by an application that uses the affected software.

Conceptual Example Code

The following example showcases a conceptual exploitation scenario. Here, a malicious file is created and then loaded into the application, triggering the out-of-bound read error.
```
#include <stdio.h>
int main() {
char buffer[10];
/* A file with more than 10 characters is loaded */
FILE *file = fopen("malicious_file", "r");
/* The application reads more data than the buffer can handle */
fread(buffer, sizeof(char), 100, file);
/* Rest of the application */
return 0;
}
```
In the above snippet, the software attempts to read 100 characters from the file into a buffer that can only hold 10 characters. This results in an out-of-bounds read and can potentially lead to arbitrary code execution.

Mitigation

Users are advised to apply the vendor patch as soon as possible to mitigate this vulnerability. In the interim, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure by detecting and blocking attempts to exploit this vulnerability.

Impact: System compromise or data leakage

Affected Products

Product | Affected Versions

Trend Micro Deep Security | 20.0

How the Exploit Works

This vulnerability stems from the improper handling of symbolic links by the affected software. When a malicious local user executes low-privileged code, the software could unintentionally follow a symbolic link that leads outside of its restricted path. This could allow the attacker to escalate his or her privileges on the system and perform unauthorized actions, potentially leading to a full system compromise or data leakage.

Conceptual Example Code

To illustrate, consider the following conceptual example of an exploit. This is a simplified representation and may not reflect the exact methods used by an attacker.
```
# Attacker creates a symbolic link to a sensitive file
ln -s /etc/shadow /tmp/vulnerable_link
# Attacker tricks the software into following the link
./vulnerable_software /tmp/vulnerable_link
```
In this example, the attacker first creates a symbolic link to a sensitive file on the system (`/etc/shadow`). The attacker then tricks the vulnerable software into following this link, potentially gaining access to sensitive data or escalating their privileges on the system.
Note that to exploit this vulnerability, an attacker must first obtain the ability to execute low-privileged code on the target system. This means that although the vulnerability is serious, its exploitation is not trivial and requires initial access to the system.

Mitigation Guidance

Trend Micro has already released a patch to address this vulnerability. It is highly recommended that users promptly apply this patch to their systems. As a temporary mitigation, users can also utilize a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to monitor and block potential exploit attempts.

How the Exploit Works

An attacker with low-level privileges on the target system can exploit this vulnerability by following a specific link in the Trend Micro Deep Security agent. This link following vulnerability allows the attacker to escalate their privileges on the system, potentially gaining full control and enabling them to compromise the system or leak sensitive data.

Conceptual Example Code

Let’s consider a conceptual scenario where an attacker might exploit this vulnerability. In this case, the attacker already has low-level privileges and is now aiming to escalate these privileges. The exploitation process might look something like this:
```
# The attacker first gains low-level access to the system
$ ssh low_privileged_user@target.system.com
# Once they have access, they exploit the link following vulnerability
$ ln -s /etc/shadow /tmp/vulnerable_link
# The attacker then follows the link
$ cat /tmp/vulnerable_link
```
In this hypothetical example, the attacker is able to read the /etc/shadow file, which contains hashed passwords for system users, due to the link following vulnerability. This could potentially allow the attacker to gain unauthorized access to other accounts on the system, depending on the strength of the passwords and hashing algorithm used.
Please note that the above example is purely conceptual and may not represent the actual exploitation process of this vulnerability. It is intended to demonstrate how an attacker might take advantage of a link following vulnerability to escalate their privileges on a system.

Conceptual Example Code

An example of how the vulnerability might be exploited is as follows:
```
$ ln -s /etc/shadow /tmp/pam_namespace
$ chmod 777 /tmp/pam_namespace
$ su -c 'cp /tmp/pam_namespace /etc/'
```
In this conceptual example, the user creates a symbolic link to the /etc/shadow file, which holds password data. They then change the permissions of the symlink to grant full access to all users. Finally, using the ‘su’ command, they copy the symlink into the /etc/ directory, effectively providing a path for privilege escalation.

Remediation Steps

The most effective way to protect against this vulnerability is to apply the vendor-supplied patch. In the absence of a patch, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. These systems can monitor and block suspicious activities, including symlink attacks and other potential exploit attempts.
