Last modified

CVE-2011-1487 is a vulnerability of currently unknown severity. The (1) lc, (2) lcfirst, (3) uc, and (4) ucfirst functions in Perl 5.10.x, 5.11.x, and 5.12.x through 5.12.3, and 5.13.x through 5.13.11, do not apply the taint attribute to the return value upon processing tainted input, which might allow context-dependent attackers to bypass the taint protection mechanism via a crafted string.. EPSS estimates a 8.71% chance of exploitation in the next 30 days.
