According to the education board, as of Tuesday, more than 400,000 students, external had applied for scanned copies of their answer-sheets and about 1.1 million had requested physical copies.
Some students complained that they faced technical glitches while applying for copies of their answer sheets, prompting federal Education Minister Dharmendra Pradhan to depute a team of experts, external from India’s top technology colleges to assist CBSE in ensuring a “glitch-free re-evaluation process”.
Students have also raised concerns about the security of the exam portal after another CBSE student claimed he hacked into it in February and was able to access evaluators’ accounts.
Nisarga Adhikary, who describes himself as an “ethical hacker”, told the BBC he was able to crack the master password for the system, gaining access to student records, answer sheets and evaluators’ accounts.
“With that kind of access, one can tamper with the answer-sheets, change marks or even access peoples’ phone numbers and bank details,” he alleged.
Adhikary said he flagged around six-to-seven security vulnerabilities he perceived in the portal to India’s Computer Emergency Response Team (CERT-IN) – a federal agency that deals with cyber-security incidents – in a series of emails, which the BBC has seen. Adhikary has also posted his findings on his X account and blog, external.
On Tuesday, CBSE denied the allegations, external, claiming that “no security breaches have come to light on the portal deployed for the actual evaluation work”.
It added that the URL flagged as being compromised was a “testing site” and that “no actual evaluation data, marks or other data [were] held on that portal”.
However, Adhikary claims that after logging into the portal, he could view scanned answer sheets and independently verify the personal details of one evaluator whose account he accessed.
“If this was a test portal, why was this information uploaded on it?” Adhikary asked.
The BBC has sent a list of questions to CBSE and CERT-IN – their response is awaited.
