We study superconducting properties of highly underdoped Cu_{0.058}TiSe_{2} single crystal by means of bulk magnetization measurements. We extract the upper critical field, H_{c2}, for magnetic field applied parallel, as well as perpendicular to the sample planes. Obtained values, H^{ab}_{c2}(0)=1.03 T and H^c_{c2}(0)=0.54 T, define a moderate anisotropy of the upper critical fields of 1.90. From the upper and lower critical fields we extract the Ginzburg-Landau parameters κ_{ab}(0)=26.3, and κ_c(0)=12.6 that classify Cu_{0.058}TiSe_{2} as an extreme type II superconductor.
