Related Weaknesses

CWE-ID Weakness Name Source
CWE-362 Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')
The product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently.

EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

Source: https://code.google.com/p/google-security-research/issues/detail?id=478 The Install.framework runner suid root binary does not correctly account for the fact that Distributed Objects can be connected to by multiple clients at the same time. By connecting two proxy objects to an IFInstallRunner and calling [IFInstallRunner makeReceiptDirAt:asRoot:] in the first and passing a custom object as the directory name we can get a callback to our code just after the makeReceiptDirAt code has called seteuid(0);setguid(0) to regain privs. Since BSD priviledges are per-process this means that our other proxy object will now have euid 0 without having to provide an authorization reference. In this second proxy we can then just call runTaskSecurely and get a root shell before returning from the first proxy's callback function which will then drop privs. build using the provided makefile and run passing the full path to the localhost shell Proof of Concept: https://gitlab.com/exploit-database/exploitdb-bin-sploits/-/raw/main/bin-sploits/38136.zip
