comment System of linear congruence, not relatively prime
Reference requests are off-topic. Solving straight dump of homework also. I suggest that you at explain (in the question, that you can edit) what you have tried and where where you are stuck in trying to applying my hint.

comment System of linear congruence, not relatively prime
Hint: use that you know the factorization of all the $m_i$ to write an equivalent system of equations where all the ${m_i}'$ are prime; check if it has solutions; and determine them using the CRT. $\;$ That can be made to work even if you do not known the factorizations of the $m_i$, by using $\gcd$. Complexity is is low, dominated by the final CRT step, I guess.

That asnwer (and question) was not based on the best known attack.

Add best known reference, tone down difficulty of breaking 2-keys 3DES.
