CVE 描述
F´ (F Prime) has Integer Overflow in FileUplink
F´ (F Prime) is a framework that enables development and deployment of spaceflight and other embedded software applications. Prior to version 4.2.0, the bounds check byteOffset + dataSize > fileSize uses U32 addition that wraps around on overflow. An attacker-crafted DataPacket with byteOffset=0xFFFFFF9C and dataSize=100 overflows to 0, bypassing the check entirely. The subsequent file write proceeds at the original ~4GB offset. Additionally, Svc/FileUplink/File.cpp:20-31 performs no sanitization on the destination file path. Combined, these allow writing arbitrary data to any file at any offset. The impact is arbitrary file write leading to remote code execution on embedded targets. Note that this is a logic bug. ASAN does not detect it because all memory accesses are within valid buffers — the corruption occurs in file I/O. Version 4.2.0 contains a patch. No known workarounds are available.CVE 信息
相关弱点
| 弱点名称 | 来源 | |
|---|---|---|
| Integer Overflow or Wraparound The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number. |
||
| Out-of-bounds Write The product writes data past the end, or before the beginning, of the intended buffer. |
EPSS
EPSS 是一种预测漏洞被利用可能性的评分模型。
EPSS 评分
EPSS 模型生成一个介于 0 到 1（即 0% 到 100%）之间的概率评分。评分越高，漏洞被利用的可能性越大。
EPSS 百分位
百分位用于根据 EPSS 评分对 CVE 进行排名。例如，EPSS 百分位为第 95 的 CVE，其被利用的可能性高于 95% 的其他 CVE。因此，百分位可用于比较不同 CVE 的 EPSS 评分。
