CVE-2025-70330: Easy Grade Pro 4.1.0.2 contains a file parsing logic flaw in the handling of proprietary .EGP gradebook files.
Easy Grade Pro 4.1.0.2 contains a file parsing logic flaw in the handling of proprietary .EGP gradebook files. By modifying specific fields at precise offsets within an otherwise valid .EGP file, an attacker can trigger an out-of-bounds memory read during parsing. This results in an unhandled access violation and application crash, leading to a local denial-of-service condition when the crafted file is opened by a user.
Security readout for executives and security teams
Plain-English summary
A crafted Easy Grade Pro gradebook file can crash the application when a user opens it. The documented impact is local denial of service, not data theft or system compromise. Business urgency is low unless the organization still depends on Easy Grade Pro workflows.
Executive priority
Treat this as a low-priority availability risk for legacy education workflows. Prioritize only where Easy Grade Pro remains operationally important or where users routinely receive gradebook files from external parties.
Technical view
CVE-2025-70330 is a CWE-125 out-of-bounds read in Easy Grade Pro 4.1.0.2 .EGP parsing. A modified but otherwise valid .EGP file can trigger an unhandled access violation and crash. CVSS 3.1 is 3.3: local attack vector, user interaction required, availability impact only.
Likely exposure
Exposure appears limited to environments where users still open proprietary .EGP gradebook files with Easy Grade Pro 4.1.0.2. The CVE affected-product metadata is incomplete, so confirm exposure through asset inventory rather than assuming wider product impact.
Exploitation context
The source describes a crafted-file crash condition. KEV is false, and the provided bundle does not cite active exploitation. Exploitation requires a user to open a malicious .EGP file locally.
Researcher notes
The public details support a local crafted-file denial of service via out-of-bounds read. The bundle does not name a patch, vendor advisory, active exploitation, or complete CPE data. Avoid expanding impact beyond application crash without more evidence.
Mitigation direction
Avoid opening .EGP gradebooks from untrusted or unexpected sources.
Restrict .EGP handling to trusted staff and managed workstations.
Check vendor or project guidance for updates before relying on a permanent fix.
Preserve backups of gradebook files to reduce operational disruption from crashes.
Validation and detection
Check inventory for Easy Grade Pro 4.1.0.2 installations.
Identify teams that exchange or archive .EGP files.
Review crash reports involving Easy Grade Pro after opening .EGP files.
Confirm user guidance warns against unexpected .EGP attachments or downloads.

These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.

Out-of-bounds Read
Out-of-bounds Read represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
