The provided information points to a potential Remote Code Execution (RCE) vulnerability targeting Microsoft Office documents. The repository, referenced by Caztemaz, appears to be related to creating malicious Office documents (DOC, DOCX, XML) that exploit vulnerabilities, leveraging a 'silent exploit builder'. The updates primarily involve modifications to a log file, likely tracking the build process or timestamping. Given the nature of the attack, this could lead to severe compromise, including system control and data theft. The description suggests targeting platforms like Office 365. However, lacking detailed information on the specific CVE, impact analysis focuses on the concept rather than specific exploitable vulnerabilities.
Analysis of the updates indicates constant revision to the log file, likely reflecting continuous development or testing iterations of the exploit builder.
| 2 | Target: Microsoft Office documents (DOC, DOCX, XML) are exploited. |
| 3 | Impact: RCE can lead to full system compromise. |
| 4 | Delivery: Malware payloads are embedded in documents to trigger exploits. |
| 5 | Platforms: Impacts Office 365 and potentially other versions. |
#### 🛠️ 技术细节
> Vulnerability: The core issue is exploiting vulnerabilities within the parsing of Office document formats to achieve RCE.
> Exploitation: Documents are crafted to trigger specific vulnerabilities when opened. This likely involves techniques like malicious macros, embedded objects, or format-specific exploits.
> Malware Payload: The exploit builder likely integrates and delivers malware payloads, such as backdoors, to establish persistence and control.
> Attack Vector: Likely delivered through phishing or social engineering, where users are tricked into opening malicious documents.

The described approach to RCE via crafted Office documents poses a significant threat. Office is widely used, the exploitation potential is very high. The presence of an exploit builder suggests ease of use, and the potential for remote code execution and system compromise makes it a critical concern. This assessment assumes successful exploitation leads to full system compromise.
The provided GitHub repository, likely associated with CVE-2025-48384, suggests a Remote Code Execution (RCE) vulnerability exploitable through a `post-checkout` Git hook. The repository currently has minimal activity, with only two commits. The initial commit establishes a baseline, while the subsequent commit modifies the `post-checkout` hook to execute arbitrary commands (touch a file in `/tmp`). The vulnerability leverages the execution of attacker-controlled code during a `git checkout` operation, which occurs frequently in development workflows. This presents a significant risk as it can lead to remote code execution if an attacker can control the contents of the repository.

| 4 | Impact: RCE, potential system compromise. |
| 5 | Vulnerability is triggered during `git checkout` operations. |
#### 🛠️ 技术细节
> The vulnerability lies in the execution of the `post-checkout` hook. If a user clones or checks out a repository containing a malicious `post-checkout` script, the script will be executed on the user's system.
> The provided POC demonstrates the ability to execute arbitrary commands by modifying the `post-checkout` script.
> Successful exploitation allows an attacker to execute commands with the privileges of the user running the `git checkout` command.
> The vulnerability is triggered by the `git checkout` command.
