An issue was discovered in Embedthis GoAhead before 4.0.1 and Appweb before 7.0.2. The server mishandles some HTTP request fields associated with time, which results in a NULL pointer dereference, as demonstrated by If-Modified-Since or If-Unmodified-Since with a month greater than 11.
Affected
Our own answer: ranges merged, affected separated from platform-only, with confidence and review flags.
v < 7.0.2
Affected range stops below 7.0.2, so it looks safe — our inference, not a vendor statement
v < 4.0.1
Affected range stops below 4.0.1, so it looks safe — our inference, not a vendor statement
