Inefficient regular expression complexity in certain Zoom Workplace Clients before version 6.5.10 may allow an unauthenticated user to conduct an escalation of privilege via network access.
The product uses a regular expression with a worst-case computational complexity that is inefficient and possibly exponential.
https://cwe.mitre.org/data/definitions/1333.html →Open in CWE collection →An adversary may execute an attack on a program that uses a poor Regular Expression(Regex) implementation by choosing input that results in an extreme situation for the Regex. A typical extreme situation operates at exponential time compared to the input size. This is due to most implementations using a Nondeterministic Finite Automaton(NFA) state machine to be built by the Regex algorithm since NFA allows backtracking and thus more complex regular expressions.
