Use the .onSelChange callback.

In NSIS 3 the changed section id is stored in $0:

Page Components
Page InstFiles

Section /o "Foo" SID_FOO
SectionEnd

Section "Bar"
SectionEnd

!include LogicLib.nsh

Function .onSelChange
${If} ${SectionIsSelected} ${SID_FOO}
${AndIf} $0 = ${SID_FOO}
    MessageBox MB_ICONEXCLAMATION "Warning, section Foo selected!"
${EndIf}
FunctionEnd

You have to track the state yourself in NSIS 2:

Page Components
Page InstFiles

Section /o "Foo" SID_FOO
SectionEnd

Section "Bar"
SectionEnd

!include LogicLib.nsh

Var hasWarned

Function .onSelChange
${If} ${SectionIsSelected} ${SID_FOO}
${AndIf} $hasWarned = 0
    StrCpy $hasWarned 1
    MessageBox MB_ICONEXCLAMATION "Warning, section Foo selected!"
${EndIf}
/* Uncomment this to display the warning every time it is selected
${IfNot} ${SectionIsSelected} ${SID_FOO}
    StrCpy $hasWarned 0
${EndIf}
*/
FunctionEnd
