Submit #798623: MikroTik RouterOS 6.49.8 Out-of-Bounds Readinfo

TitleMikroTik RouterOS 6.49.8 Out-of-Bounds Read
DescriptionAn out-of-bounds read vulnerability exists in the nova/lib/www/scep.p component of MikroTik RouterOS firmware. The SCEP server parses attacker-controlled PKCS#7 signed attributes such as transactionID and messageType by returning raw ASN1_STRING_data() pointers and later consuming those values with NUL-terminated C-string semantics. An attacker who can reach an enabled SCEP endpoint can send a crafted PKIOperation request containing a non-NUL-terminated ASN.1 PrintableString and trigger reads beyond the original ASN.1 attribute boundary, leading to pre-authentication information disclosure in certRep replies and abnormal parser behavior.
