Lifecycle Timeline
1DescriptionCVE.org
A heap-based buffer overflow vulnerability exists in the Programming Software Connection CurrDir functionality of AutomationDirect P3-550E 1.2.10.9. A specially crafted network packet can lead to denial of service. An attacker can send an unauthenticated packet to trigger these vulnerability.This CVE tracks the heap corruption that occurs at offset 0xb68c4 of version 1.2.10.9 of the P3-550E firmware, which occurs when a call to memset relies on an attacker-controlled length value and corrupts any trailing heap allocations.
AnalysisAI
A heap-based buffer overflow vulnerability exists in the Programming Software Connection CurrDir functionality of AutomationDirect P3-550E 1.2.10.9. Rated high severity (CVSS 8.2), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
Technical ContextAI
This vulnerability is classified as Out-of-bounds Write (CWE-787), which allows attackers to write data beyond allocated buffer boundaries leading to code execution or crashes. A heap-based buffer overflow vulnerability exists in the Programming Software Connection CurrDir functionality of AutomationDirect P3-550E 1.2.10.9. A specially crafted network packet can lead to denial of service. An attacker can send an unauthenticated packet to trigger these vulnerability.This CVE tracks the heap corruption that occurs at offset 0xb68c4 of version 1.2.10.9 of the P3-550E firmware, which occurs when a call to memset relies on an attacker-controlled length value and corrupts any trailing heap allocations. Affected products include: Automationdirect P3-550E Firmware, Automationdirect P3-550 Firmware, Automationdirect P3-530 Firmware, Automationdirect P2-550 Firmware, Automationdirect P1-550 Firmware. Version information: version 1.2.10.9.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate write boundaries, use memory-safe languages, enable compiler protections (ASLR, stack canaries).
