In its section on Quotations and Dialogue: Permissible changes to punctuation, capitalization, and spelling, the Chicago Manual of Style recommends:

Obvious typographic errors may be corrected silently (without comment or sic; see 13.59), unless the passage quoted is from an older work or a manuscript source where idiosyncrasies of spelling are generally preserved. If spelling and punctuation are modernized or altered for clarity, readers must be so informed in a note, in a preface, or elsewhere.

The choice is yours: make the correction and move on, or correct the text and flag it with a footnote[1].

However, the example you cite apparently isn't from an ancient manuscript, and your correction isn't modernizing it or altering it for clarity, so I would simply make the correction without comment.
