CVE-2010-20120: Maple <= v13 Maplet File Creation and Command Execution
Maple versions up to and including 13's Maplet framework allows embedded commands to be executed automatically when a .maplet file is opened. This behavior bypasses standard security restrictions that normally prevent code execution in regular Maple worksheets. The vulnerability enables attackers to craft malicious .maplet files that execute arbitrary code without user interaction.
Security readout for executives and security teams
Plain-English summary
Opening a malicious Maple Maplet file can run commands on a user's machine. The source bundle describes this as affecting Maple versions up to and including 13. It requires a user to open the file, but public exploit references exist, so legacy Maple environments should treat this as a serious file-handling risk.
Executive priority
Prioritize remediation where legacy Maple is used on workstations handling external files. This is not described as remotely exploitable without user action, but public exploit material raises risk for targeted phishing or file-sharing attacks.
Technical view
The issue is command execution through Maple's Maplet framework, where embedded commands in a .maplet file execute automatically when opened, bypassing worksheet security restrictions. The bundle maps this to CWE-94 and CVSS 4.0 score 8.4. Affected-version metadata is incomplete or inconsistent, but the description states Maple <=13.
Likely exposure
Most exposure is likely in academic, engineering, scientific, or legacy desktop environments where Maple 13 or earlier remains installed and users can open .maplet files from email, downloads, or shared drives.
Exploitation context
The bundle includes public Exploit-DB and Metasploit references, indicating public exploit material exists. It does not cite CISA KEV listing or active exploitation. Exploitation appears local and user-assisted because the file must be opened.
Researcher notes
Evidence supports arbitrary command execution through Maplet file opening. Do not assume active exploitation from the provided sources. The affected field in the bundle is not clean, so validation should rely on the narrative claim of Maple <=13 and vendor confirmation.
Mitigation direction
Inventory Maple installations and prioritize versions 13 or earlier.
Check Maplesoft guidance for supported upgrades, patches, or official mitigations.
Restrict or quarantine untrusted .maplet files at mail and web gateways.
Limit Maple file associations on systems that do not need Maplet support.
Review Juniper IPS coverage for the referenced Maplet command-execution signature.
Validation and detection
Confirm whether Maple 13 or earlier is installed on managed endpoints.
Search mail, download, and file-share telemetry for untrusted .maplet files.
Verify endpoint controls warn, block, or quarantine suspicious Maplet files.
Check IDS or IPS logs for the Juniper Maplet signature name.
Document any affected business groups and their upgrade path.

CWE-94: Code execution behavior lookup
Code execution and unsafe deserialization weaknesses often justify reviewing execution behavior and process telemetry. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
The CVE wording references code or command execution, so execution technique review may help defensive triage. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.

Improper Control of Generation of Code ('Code Injection')
Improper Control of Generation of Code ('Code Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
