CVE-2010-2572 is a buffer overflow vulnerability in Microsoft PowerPoint. CISA added it to the Known Exploited Vulnerabilities catalogue on 8 June 2022, which means attackers have used it in real attacks. Microsoft PowerPoint contains a buffer overflow vulnerability that alllows for remote code execution.
What a buffer overflow in PowerPoint means
A buffer overflow means PowerPoint can be made to write past the memory it intended to use. In a document parser or rendering path, that kind of memory corruption can move from a crash to attacker-controlled code execution, which is why seemingly ordinary presentation files can become an entry point.
For CVE context, the practical significance is not the label alone but the combination of a widely used desktop application, file-based delivery, and the possibility of remote code execution when a crafted file is opened.
Why this vulnerability is dangerous
PowerPoint sits in a high-trust position because users routinely open files from email, shared drives, collaboration platforms and external sources. A memory corruption bug in that workflow can be used to turn document handling into an execution path, especially when the user is merely previewing or opening the file as part of normal work.
Attackers favour this class of issue because the victim does not need to visit a malicious website or install software. The file itself becomes the payload, and the exploit can be delivered through channels that look routine to both users and security tools.
For a broader view of how exploited flaws are tracked and prioritised, see the NIST National Vulnerability Database and the CVE Program.
How organisations assess exposure
The first question is whether PowerPoint is present on endpoints, VDI images, terminal servers, shared workstations and any systems that process untrusted Office documents. Exposure is not just whether the product exists, but whether it is reachable by users who regularly handle externally supplied files.
Teams should also look at internet-facing workflows that accept documents, such as upload portals, email gateways and collaboration integrations, because those paths often determine how quickly a malicious presentation can reach a target. Vendor advisories and vulnerability intelligence should then be used to confirm whether the specific product build is affected and how urgently remediation should be scheduled.
For operational prioritisation of exploited vulnerabilities, the Vulnerability Management Guide is a useful companion for asset scoping, KEV-based prioritisation and verification. The CWE Top 25 Guide also helps explain why buffer overflows remain a severe weakness class, even when the exact exploitation path differs by product.
Remediation, detection and post-compromise review
Remediation should follow the vendor’s guidance for the exact affected build, with patching treated as the primary fix and compensating controls used only while exposure remains. If patching is delayed, reduce exposure by tightening document handling paths, limiting where untrusted files can be opened, and using layered controls that can interrupt exploit delivery or execution.
Detection should focus on suspicious file-opening activity followed by abnormal PowerPoint behaviour, unexpected child processes, crash patterns, or other signs that a presentation file has triggered memory corruption. After patching, review whether the endpoint showed signs of compromise before the fix, because successful exploitation can leave behind persistence, dropped payloads or credential theft that the patch itself will not remove.
Because exploited document flaws are often used as initial access, a post-incident review should also consider whether the device held signed-in sessions, cached credentials or access tokens that need to be invalidated.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
NIST SP 800-53 Rev 5 and CIS Controls v8 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST SP 800-53 Rev 5 | SI-2 — Flaw Remediation | Buffer overflow exposure requires timely flaw remediation and patch validation. |
| SI-3 — Malicious Code Protection | Document-delivered exploitation is often caught or disrupted by malware protection controls. | |
| AU-6 — Audit Review, Analysis, and Reporting | Post-exploitation review depends on log analysis to spot suspicious document-opening activity and follow-on actions. | |
| Recommendation — Prioritise and verify remediation for the vulnerable PowerPoint build. Use malicious code protection to inspect and block weaponised presentation files. Review logs for anomalous file execution and post-open process activity. | ||
| CIS Controls v8 | CIS-7 — Continuous Vulnerability Management | An exploited CVE belongs in continuous vulnerability prioritisation and remediation workflows. |
| CIS-8 — Audit Log Management | Detection and compromise review depend on retaining and reviewing logs around document handling and endpoint execution. | |
| Recommendation — Track exposed PowerPoint systems and drive patching through vulnerability management. Collect and review endpoint and gateway logs for suspicious document-triggered activity. | ||
Practitioner Guidance
Why practitioners should care: Treat this as more than a software defect, because an exploited presentation parser can become an initial-access path into user workstations and, from there, into broader enterprise environments. The operational question is not just whether the application runs, but whether it is exposed to untrusted files in ways that make exploitation plausible.
Common misunderstanding: Teams sometimes assume Office documents are low risk because they are familiar business artifacts. In practice, familiar file types are often attractive delivery vehicles precisely because users and mail controls are less suspicious of them than of executables.
Practitioner takeaway: Prioritise the affected PowerPoint exposure based on where untrusted documents enter the environment, then validate that detection, patching and compromise review are all aligned to that real-world file flow.
